Round borders separated in sections around circular image - border

I am wondering how it is possible to create the following effect using only CSS:
Desired output :
Currently, all I can think of is adding a border around the image. But how can I cut them and make sections out of them around the image?
This is my current CSS:
.avatar img {
border-radius: 50%;
border: solid 3px #65C178;
border-width: 4px;
}
And HTML:
<div class="avatar"><img src="https://s3.amazonaws.com/uifaces/faces/twitter/soffes/128.jpg" /></div>
Preview: JSFiddle Example
This only gives a border around the avatar image, not the green sections with white spacings.

DEMO
Output :
Explanation
Creating the borders
Use borders with border-radius to create the borders.
step 1
Then transform rotate to make the left top border appear at the right place.Step 2 (don't forget to "unrotate" the image by rotating it the other way so it stays vertical)
The white spaces
Use pseudo elements to create the white spacings at the bottom and the right of the image. step 3
Unless you have very special requirements for browser support, you can remove the vendor prefixes for the border-radius property. Check canIuse for more info.
CSS :
.avatar{
border: solid 4px #54BE69;
border-left-color:#D5EDDA;
padding:2px;
display:inline-block;
border-radius: 50%;
position:relative;
transform:rotate(45deg);
-ms-transform:rotate(45deg);
-webkit-transform:rotate(45deg);
}
.avatar img{
display:block;
border-radius: 50%;
transform:rotate(-45deg);
-ms-transform:rotate(-45deg);
-webkit-transform:rotate(-45deg);
}
.avatar:before, .avatar:after{
content:'';
position:absolute;
background:#fff;
z-index:-1;
transform:rotate(-45deg);
-ms-transform:rotate(-45deg);
-webkit-transform:rotate(-45deg);
}
.avatar:before{
height:4px;
top:50%;
left:2px; right:-5px;
margin-top:-2px;
}
.avatar:after{
width:4px;
left:50%;
top:2px; bottom:-5px;
margin-left:-2px;
}

Here you have an example with sass.. (quickly Googled)

EDIT: As requested in comments here's a little improvement with some quick tweaks to that codepen

SASS:
// Colors
$progressColor: #65C178
$pendingProgressColor: #D5EDDA
$backColor: #fff
/* -------------------------------------
* Avatar img
* ------------------------------------- */
.avatar img
border-radius: 50%
border: solid 3px #fff
border-width: 3px
margin-top: 4px

$half: round($loops / 2)
#for $i from 0 through $loops
.progress-#{$i*$step}
#if $i < $half
$nextdeg: 90deg + ( $increment * $i )
background-image: linear-gradient(90deg, $pendingProgressColor 50%, transparent 50%, transparent), linear-gradient($nextdeg, $progressColor 50%, $pendingProgressColor 50%, $pendingProgressColor)
#else
$nextdeg: -90deg + ( $increment * ( $i - $half ) )
background-image: linear-gradient($nextdeg, $progressColor 50%, transparent 50%, transparent), linear-gradient(270deg, $progressColor 50%, $pendingProgressColor 50%, $pendingProgressColor)
For the separator of the progress sections another mixin could be included

here is a solution: jsfiddle
CSS
.avatar img {
border-radius: 50%;
border-width: 4px;
padding: 4px;
background-image: linear-gradient(-90deg, #65C178 50%, rgba(0, 0, 0, 0) 50%), linear-gradient(0deg, #65C178 50%, rgba(0, 0, 0, 0) 50%);
}
HTML
<div class="avatar">
<img src="https://s3.amazonaws.com/uifaces/faces/twitter/soffes/128.jpg" />
</div>
Note: change the deg value in the second linear-gradient to change the percentage filled.

We cant get the exact like your image. But something we can get it. Add the following line of code in your css.
border-top-color:#ff00ff;
border-bottom-color:#0000ff;
border-left-color:#00ff00;
border-right-color:#000;

BORDER DOTTED-CSS SPACING [duplicate]

I am using dotted style border in my box like
.box {
width: 300px;
height: 200px;
border: dotted 1px #f00;
float: left;
}
I want to the increase the space between each dot of the border.
This trick works for both horizontal and vertical borders:
/*Horizontal*/
background-image: linear-gradient(to right, black 33%, rgba(255,255,255,0) 0%);
background-position: bottom;
background-size: 3px 1px;
background-repeat: repeat-x;
/*Vertical*/
background-image: linear-gradient(black 33%, rgba(255,255,255,0) 0%);
background-position: right;
background-size: 1px 3px;
background-repeat: repeat-y;
You can adjust the size with background-size and the proportion with the linear-gradient percentages. In this example I have a dotted line of 1px dots and 2px spacing.
This way you can have multiple dotted borders too using multiple backgrounds.
Try it in this JSFiddle or take a look at the code snippet example:
div {
padding: 10px 50px;
}
.dotted {
border-top: 1px #333 dotted;
}
.dotted-gradient {
background-image: linear-gradient(to right, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: top;
background-size: 3px 1px;
background-repeat: repeat-x;
}
.dotted-spaced {
background-image: linear-gradient(to right, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: top;
background-size: 10px 1px;
background-repeat: repeat-x;
}
.left {
float: left;
padding: 40px 10px;
background-color: #F0F0DA;
}
.left.dotted {
border-left: 1px #333 dotted;
border-top: none;
}
.left.dotted-gradient {
background-image: linear-gradient(to bottom, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: left;
background-size: 1px 3px;
background-repeat: repeat-y;
}
.left.dotted-spaced {
background-image: linear-gradient(to bottom, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: left;
background-size: 1px 10px;
background-repeat: repeat-y;
}

Here's a trick I've used on a recent project to achieve nearly anything I want with horizontal borders. I use <hr/> each time I need an horizontal border. The basic way to add a border to this hr is something like
hr {border-bottom: 1px dotted #000;}
But if you want to take control of the border and, for example increase, the space between dots, you may try something like this:
hr {
height:14px; /* specify a height for this hr */
overflow:hidden;
}
And in the following, you create your border (here's an example with dots)
hr:after {
content:".......................................................................";
letter-spacing: 4px; /* Use letter-spacing to increase space between dots*/
}
This also means that you can add text-shadow to the dots, gradients etc. Anything you want...
Well, it works really great for horizontal borders. If you need vertical ones, you may specify a class for another hr and use the CSS3 rotation property.
You cannot do it with pure CSS - the CSS3 spec even has a specific quote about this:
Note: There is no control over the spacing of the dots and dashes, nor over the length of the dashes. Implementations are encouraged to choose a spacing that makes the corners symmetrical.
You can, however, use either a border-image or a background image that does the trick.
This uses the standard CSS border and a pseudo element+overflow:hidden.
In the example you get three different 2px dashed borders: normal, spaced like a 5px, spaced like a 10px. Is actually 10px with only 10-8=2px visible.
div.two{border:2px dashed #FF0000}
div.five:before {
content: "";
position: absolute;
border: 5px dashed #FF0000;
top: -3px;
bottom: -3px;
left: -3px;
right: -3px;
}
div.ten:before {
content: "";
position: absolute;
border: 10px dashed #FF0000;
top: -8px;
bottom: -8px;
left: -8px;
right: -8px;
}
div.odd:before {left:0;right:0;border-radius:60px}
div {
overflow: hidden;
position: relative;
text-align:center;
padding:10px;
margin-bottom:20px;
}
<div class="two">Kupo nuts here</div>
<div class="five">Kupo nuts<br/>here</div>
<div class="ten">Kupo<br/>nuts<br/>here</div>
<div class="ten odd">Kupo<br/>nuts<br/>here</div>
Applied to small elements with big rounded corners may make for some fun effects.
So starting with the answer given and applying the fact that CSS3 allows multiple settings - the below code is useful for creating a complete box:
#border {
width: 200px;
height: 100px;
background: yellow;
text-align: center;
line-height: 100px;
background: linear-gradient(to right, orange 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(blue 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(to right, green 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(red 50%, rgba(255, 255, 255, 0) 0%);
background-position: top, right, bottom, left;
background-repeat: repeat-x, repeat-y;
background-size: 10px 1px, 1px 10px;
}
<div id="border">
bordered area
</div>
Its worth noting that the 10px in the background size gives the area that the dash and gap will cover. The 50% of the background tag is how wide the dash actually is. It is therefore possible to have different length dashes on each border side.
Late to the party but I found that neat little tool online.
https://kovart.github.io/dashed-border-generator/
See the MDN docs for the available values for border-style:
none : No border, sets width to 0.
This is the default value.
hidden : Same as 'none', except in terms of
border conflict resolution for table
elements.
dashed : Series of short
dashes or line segments.
dotted :
Series of dots.
double : Two straight
lines that add up to the pixel amount
defined as border-width.
groove :
Carved effect.
inset : Makes the box
appear embedded.
outset : Opposite of
'inset'. Makes the box appear 3D
(embossed).
ridge : Opposite of
'groove'. The border appears 3D
(coming out).
solid : Single,
straight, solid line.
Apart from those choices, there is no way to influence the standard border's style.
If the possibilities there are not to your liking, you could use CSS3's border-image but note that browser support for this is still very spotty (EDIT: browser support is good as of 2020).
This is an old, but still very relevant topic. The current top answer works well, but only for very small dots. As Bhojendra Rauniyar already pointed out in the comments, for larger (>2px) dots, the dots appear square, not round. I found this page searching for spaced dots, not spaced squares (or even dashes, as some answers here use).
Building on this, I used radial-gradient. Also, using the answer from Ukuser32, the dot-properties can easily be repeated for all four borders. Only the corners are not perfect.
div {
padding: 1em;
background-image:
radial-gradient(circle at 2.5px, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle at 2.5px, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle, #000 1.25px, rgba(255,255,255,0) 2.5px);
background-position: top, right, bottom, left;
background-size: 15px 5px, 5px 15px;
background-repeat: repeat-x, repeat-y;
}
<div>Some content with round, spaced dots as border</div>
The radial-gradient expects:
the shape and optional position
two or more stops: a color and radius
Here, I wanted a 5 pixel diameter (2.5px radius) dot, with 2 times the diameter (10px) between the dots, adding up to 15px. The background-size should match these.
The two stops are defined such that the dot is nice and smooth: solid black for half the radius and than a gradient to the full radius.
Building 4 edges solution basing on #Eagorajose's answer with shorthand syntax:
background: linear-gradient(to right, #000 33%, #fff 0%) top/10px 1px repeat-x, /* top */
linear-gradient(#000 33%, #fff 0%) right/1px 10px repeat-y, /* right */
linear-gradient(to right, #000 33%, #fff 0%) bottom/10px 1px repeat-x, /* bottom */
linear-gradient(#000 33%, #fff 0%) left/1px 10px repeat-y; /* left */
#page {
background: linear-gradient(to right, #000 33%, #fff 0%) top/10px 1px repeat-x, /* top */
linear-gradient(#000 33%, #fff 0%) right/1px 10px repeat-y, /* right */
linear-gradient(to right, #000 33%, #fff 0%) bottom/10px 1px repeat-x, /* bottom */
linear-gradient(#000 33%, #fff 0%) left/1px 10px repeat-y; /* left */
width: 100px;
height: 100px;
}
<div id="page"></div>
This is a really old question but it has a high ranking in Google so I'm going to throw in my method which could work depending on your needs.
In my case, I wanted a thick dashed border that had a minimal break in between dashes. I used a CSS pattern generator (like this one: http://www.patternify.com/) to create a 10px wide by 1px tall pattern. 9px of that is solid dash color, 1px is white.
In my CSS, I included that pattern as the background image, and then scaled it up by using the background-size attribute. I ended up with a 20px by 2px repeated dash, 18px of that being solid line and 2px white. You could scale it up even more for a really thick dashed line.
The nice thing is since the image is encoded as data you don't have the additional outside HTTP request, so there's no performance burden. I stored my image as a SASS variable so I could reuse it in my site.
So many people are say "You can't". Yes you can. It's true that there is not a css rule to control the gutter space between the dashes but css has other abilities. Don't be so quick to say that a thing can not be done.
.hr {
border-top: 5px dashed #CFCBCC;
margin: 30px 0;
position: relative;
}
.hr:before {
background-color: #FFFFFF;
content: "";
height: 10px;
position: absolute;
top: -2px;
width: 100%;
}
.hr:after {
background-color: #FFFFFF;
content: "";
height: 10px;
position: absolute;
top: -13px;
width: 100%;
}
Basically the border-top height (5px in this case) is the rule that determines the gutter "width". OIf course you would need to adjust the colors to match your needs. This also is a small example for a horizontal line, use left and right to make the vertical line.
In my case I needed curved corners and thin border so I came up with this solution:
/* For showing dependencies between attributes */
:root {
--border-width: 1px;
--border-radius: 4px;
--bg-color: #fff;
}
/* Required: */
.dropzone {
position: relative;
border: var(--border-width) solid transparent;
border-radius: var(--border-radius);
background-clip: padding-box;
background-color: var(--bg-color);
}
.dropzone::before {
content: '';
position: absolute;
top: calc(var(--border-width) * -1); /* or without variables: 'top: -1px;' */
right: calc(var(--border-width) * -1);
bottom: calc(var(--border-width) * -1);
left: calc(var(--border-width) * -1);
z-index: -1;
background-image: repeating-linear-gradient(135deg, transparent 0 8px, var(--bg-color) 8px 16px);
border-radius: var(--border-radius);
background-color: rgba(0, 0, 0, 0.38);
}
/* Optional: */
html {
background-color: #fafafb;
display: flex;
justify-content: center;
}
.dropzone {
box-sizing: border-box;
height: 168px;
padding: 16px;
display: flex;
align-items: center;
justify-content: center;
cursor: pointer;
}
.dropzone::before {
transition: background-color 0.2s ease-in-out;
}
.dropzone:hover::before {
background-color: rgba(0, 0, 0, 0.87);
}
<div class='dropzone'>

The idea is to put svg pattern behind element and display only thin line of this pattern as element border.
Short answer: You can't.
You will have to use border-image property and a few images.
IF you're only targeting modern browsers, AND you can have your border on a separate element from your content, then you can use the CSS scale transform to get a larger dot or dash:
border: 1px dashed black;
border-radius: 10px;
-webkit-transform: scale(8);
transform: scale(8);
It takes a lot of positional tweaking to get it to line up, but it works. By changing the thickness of the border, the starting size and the scale factor, you can get to just about thickness-length ratio you want. Only thing you can't touch is dash-to-gap ratio.
<div style="width: 100%; height: 100vh; max-height: 20px; max-width: 100%; background: url('https://kajabi-storefronts-production.global.ssl.fastly.net/kajabi-storefronts-production/themes/853636/settings_images/Ei2yf3t7TvyRpFaLQZiX_dot.jpg') #000; background-repeat: repeat;"> </div>
this is what I did - use an image
enter image description here
I made a javascript function to create dots with an svg. You can adjust dot spacing and size in the javascript code.
var make_dotted_borders = function() {
// EDIT THESE SETTINGS:
var spacing = 8;
var dot_width = 2;
var dot_height = 2;
//---------------------
var dotteds = document.getElementsByClassName("dotted");
for (var i = 0; i < dotteds.length; i++) {
var width = dotteds[i].clientWidth + 1.5;
var height = dotteds[i].clientHeight;
var horizontal_count = Math.floor(width / spacing);
var h_spacing_percent = 100 / horizontal_count;
var h_subtraction_percent = ((dot_width / 2) / width) * 100;
var vertical_count = Math.floor(height / spacing);
var v_spacing_percent = 100 / vertical_count;
var v_subtraction_percent = ((dot_height / 2) / height) * 100;
var dot_container = document.createElement("div");
dot_container.classList.add("dot_container");
dot_container.style.display = getComputedStyle(dotteds[i], null).display;
var clone = dotteds[i].cloneNode(true);
dotteds[i].parentElement.replaceChild(dot_container, dotteds[i]);
dot_container.appendChild(clone);
for (var x = 0; x < horizontal_count; x++) {
// The Top Dots
var dot = document.createElement("div");
dot.classList.add("dot");
dot.style.width = dot_width + "px";
dot.style.height = dot_height + "px";
var left_percent = (h_spacing_percent * x) - h_subtraction_percent;
dot.style.left = left_percent + "%";
dot.style.top = (-dot_height / 2) + "px";
dot_container.appendChild(dot);
// The Bottom Dots
var dot = document.createElement("div");
dot.classList.add("dot");
dot.style.width = dot_width + "px";
dot.style.height = dot_height + "px";
dot.style.left = (h_spacing_percent * x) - h_subtraction_percent + "%";
dot.style.top = height - (dot_height / 2) + "px";
dot_container.appendChild(dot);
}
for (var y = 1; y < vertical_count; y++) {
// The Left Dots:
var dot = document.createElement("div");
dot.classList.add("dot");
dot.style.width = dot_width + "px";
dot.style.height = dot_height + "px";
dot.style.left = (-dot_width / 2) + "px";
dot.style.top = (v_spacing_percent * y) - v_subtraction_percent + "%";
dot_container.appendChild(dot);
}
for (var y = 0; y < vertical_count + 1; y++) {
// The Right Dots:
var dot = document.createElement("div");
dot.classList.add("dot");
dot.style.width = dot_width + "px";
dot.style.height = dot_height + "px";
dot.style.left = width - (dot_width / 2) + "px";
if (y < vertical_count) {
dot.style.top = (v_spacing_percent * y) - v_subtraction_percent + "%";
}
else {
dot.style.top = height - (dot_height / 2) + "px";
}
dot_container.appendChild(dot);
}
}
}
make_dotted_borders();
div.dotted {
display: inline-block;
padding: 0.5em;
}
div.dot_container {
position: relative;
margin-left: 0.25em;
margin-right: 0.25em;
}
div.dot {
position: absolute;
content: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" height="100" width="100"><circle cx="50" cy="50" r="50" fill="black" /></svg>');
}
<div class="dotted">Lorem Ipsum</div>
You could create a canvas (via javascript) and draw a dotted line within. Within the canvas you can control how long the dash and the space in between shall be.
We needed to have circles and this is how we solved it :)
More or less this is done to the element where the styled "border" is needed:
:before {
position: absolute;
width: 100%;
height: 10px;
top:0;
left: 0;
transform: translateY(-50%);
content: '';
background: url("data:image/svg+xml;charset=UTF-8,%3csvg viewBox='0 0 18 10' xmlns='http://www.w3.org/2000/svg'%3e%3ccircle cx='5' cy='5' r='5' fill='%23f7f7f7'/%3e%3c/svg%3e");
}
Demo: https://codepen.io/arnoldsv/pen/PoWYxbg
Here's a solution using CSS only with the use of a clip-path to mask the excess border. Unlike the most voted answer this allows for transparent backgrounds. You can also use get rounded borders by matching the clip-path round property to the border-radius.
.demo {
display: inline-flex;
width: 200px;
height: 100px;
position: relative;
clip-path: inset(0 round 30px 0 30px 0);
}
.demo::before {
content: '';
position: absolute;
left: -7px;
top: -7px;
right: -7px;
bottom: -7px;
border: 8px dashed rgba(0, 0, 255, 0.3);
border-radius: 37px 0 37px 0;
box-sizing: border-box;
}
<div class="demo"></div>
Here's a sass mixin for those interested
=dashed-border($size: 5px, $thickness: 1px, $color: black, $round: 0px)
$corners: ''
#for $i from 1 through length($round)
$value: nth($round, $i)
#if $value != 0
$corners: unquote($corners + calc(#{$value} - #{$size}) + ' ')
#else
$corners: unquote($corners + #{$value} + ' ')
clip-path: inset(0 round $corners)
&::before
content: ''
position: absolute
left: - $size + $thickness
top: - $size + $thickness
right: - $size + $thickness
bottom: - $size + $thickness
border: $size dashed $color
border-radius: $round
box-sizing: border-box
AFAIK there isn't a way to do this. You could use a dashed border or perhaps increase the width of the border a bit, but just getting more spaced out dots is impossible with CSS.

How to add an edge highlight to a CSS shape?

Hi I am trying to create a highlight on a CSS shape as shown below.
There will also be content inside of the hexagon including image and text,
The highlight I am referring to is the part in the top left.
the code I currently have for creating the hexagon is:
HTML
<div class="hexagon-big"></div>
CSS
.hexagon-big {
position: relative;
width: 200px;
height: 115.47px;
background-color: #343434;
}
.hexagon-big:before,
.hexagon-big:after {
content: "";
position: absolute;
width: 0;
border-left: 100px solid transparent;
border-right: 100px solid transparent;
}
.hexagon-big:before {
bottom: 100%;
border-bottom: 57.74px solid #343434;
}
.hexagon-big:after {
top: 100%;
width: 0;
border-top: 57.74px solid #343434;
}
There is other code for the content but i left it out because I don't think it is necessary
Do the hexagon shape differently and you can rely on gradient to create that highlight effect:
.hex {
width: 200px;
display: inline-flex;
margin:0 5px;
background:
conic-gradient(at top,#000 230deg, #0000 0),
linear-gradient(to bottom left,#fff , #000 60%);
clip-path: polygon(0% 25%,0% 75%,50% 100%,100% 75%,100% 25%,50% 0%);
}
.hex::before {
content: "";
padding-top: 115%; /* 100%/cos(30) */
}
<div class="hex"></div>
The solution in this answer is heavily based on the previous answer. To use clip-path and stacked gradients is by far the smartest thing to do here, but I still wanted to post this in order to show, how this solution could be improved and adjusted for your use case (text box, coloring, variables for maintenance, etc.).
.hexagon-big {
/* define box and text space */
width: 200px;
height: 230px;
padding: 10.8% 5px; /* adjust text box padding here; mind that top/bottom tip are part of the box */
box-sizing: border-box; /* width/height should include padding */
/* text formatting (optional) */
color: white;
text-align: center;
/* hex shape */
--hex-col: hsl(0deg 0% 20%); /* just your #343434 as a HSL color */
--hex-shadow: hsl(0deg 0% 50%); /* increased lightness by 15% to define highlight root color; 100% would be fully white */
background:
conic-gradient(at top, var(--hex-col) 232deg, transparent 0), /* change the angle of the shadow at "232deg": increase → narrower, decrease → wider */
linear-gradient(to bottom left, var(--hex-shadow), var(--hex-col) 55%);
clip-path: polygon(0% 25%,0% 75%,50% 100%,100% 75%,100% 25%,50% 0%);
}
<div class="hexagon-big">
Lorem ipsum dolor sit amet...
</div>
It should also be mentioned that your current way of using border is well better supported by older browsers than clip-path and conic-gradient (same with var()).
If this should be a problem, you might have to add another HTML tag and work out a way with transform: matrix(...) and box-shadow: inset ... (for example).

CSS - fading gradient border from-to

I want to make my whole div section with fading border. Here is my code:
.usermanagement {
-webkit-border-image: -webkit-gradient(
linear,
left top,
left bottom,
from(#fff),
to(#afd4ec),
color-stop(0.2, #afd4ec)
)
0 0 0 0 repeat repeat;
}
The effect is exactly what I want but only for top:
Then all goes to light blue and finishes like this:
Without this fading effect. I want to make the same effect as in the top for the bottom end of the section. How it is possible?
You can try like below. make sure to correctly set the different values.
.box {
height:50px; /* this need to be a multiple of 10 for the effect to work */
border-top: 10px solid;
border-bottom:10px solid;
background:#f2f2f2;
border-image:repeating-linear-gradient(#fff 0,red 10px) 10;
}
<div class="box"></div>
You can also do it with multiple background:
.box {
height:50px;
border-top:10px solid transparent;
border-bottom:10px solid transparent;
background:
linear-gradient(#fff ,red ) top,
linear-gradient(#fff ,red ) bottom, /* use (red, #fff) here for the opposite effect */
#f2f2f2;
background-size:100% 10px;
background-origin:border-box;
background-repeat:no-repeat;
}
<div class="box"></div>

How to make a transparent border using CSS?

I'm trying to do something like this for a client who has a blog.
She wanted a semi transparent border. I know that's possible with making it just a background. But I can't seem to find the logic/code behind this kind of css technique for banners. Does anybody know how to do this? It would be a lot of help because that's the look my client's wanting to achieve for his blog....
Well if you want fully transparent than you can use
border: 5px solid transparent;
If you mean opaque/transparent, than you can use
border: 5px solid rgba(255, 255, 255, .5);
Here, a means alpha, which you can scale, 0-1.
Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.
For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.
Demo
Demo 2 (With a background image for nested div)
Demo 3 (With an img tag instead of a background-image)
body {
background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);
}
div.wrap {
border: 5px solid #fff; /* Fall back, not used in fiddle */
border: 5px solid rgba(255, 255, 255, .5);
height: 400px;
width: 400px;
margin: 50px;
border-radius: 50%;
}
div.inner {
background: #fff; /* Fall back, not used in fiddle */
background: rgba(255, 255, 255, .5);
height: 380px;
width: 380px;
border-radius: 50%;
margin: auto; /* Horizontal Center */
margin-top: 10px; /* Vertical Center ... Yea I know, that's
manually calculated*/
}
Note (For Demo 3): Image will be scaled according to the height and
width provided so make sure it doesn't break the scaling ratio.
You can also use border-style: double with background-clip: padding-box, without the use of any extra (pseudo-)elements. It's probably the most compact solution, but not as flexible as the others.
For example:
<div class="circle">Some text goes here...</div>
.circle{
width: 100px;
height: 100px;
padding: 50px;
border-radius: 200px;
border: double 15px rgba(255,255,255,0.7);
background: rgba(255,255,255,0.7);
background-clip: padding-box;
}
If you look closely you can see that the edge between the border and the background is not perfect. This seems to be an issue in current browsers. But it's not that noticeable when the border is small.
Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:
LIVE DEMO
<div class="circle"></div>
CSS:
.circle, .circle:before{
position:absolute;
border-radius:150px;
}
.circle{
width:200px;
height:200px;
z-index:0;
margin:11%;
padding:40px;
background: hsla(0, 100%, 100%, 0.6);
}
.circle:before{
content:'';
display:block;
z-index:-1;
width:200px;
height:200px;
padding:44px;
border: 6px solid hsla(0, 100%, 100%, 0.6);
/* 4px more padding + 6px border = 10 so... */
top:-10px;
left:-10px;
}
The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.
use rgba (rgb with alpha transparency):
border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity
The alpha transparency variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)

How to increase space between dotted border dots

I am using dotted style border in my box like
.box {
width: 300px;
height: 200px;
border: dotted 1px #f00;
float: left;
}
I want to the increase the space between each dot of the border.
This trick works for both horizontal and vertical borders:
/*Horizontal*/
background-image: linear-gradient(to right, black 33%, rgba(255,255,255,0) 0%);
background-position: bottom;
background-size: 3px 1px;
background-repeat: repeat-x;
/*Vertical*/
background-image: linear-gradient(black 33%, rgba(255,255,255,0) 0%);
background-position: right;
background-size: 1px 3px;
background-repeat: repeat-y;
You can adjust the size with background-size and the proportion with the linear-gradient percentages. In this example I have a dotted line of 1px dots and 2px spacing.
This way you can have multiple dotted borders too using multiple backgrounds.
Try it in this JSFiddle or take a look at the code snippet example:
div {
padding: 10px 50px;
}
.dotted {
border-top: 1px #333 dotted;
}
.dotted-gradient {
background-image: linear-gradient(to right, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: top;
background-size: 3px 1px;
background-repeat: repeat-x;
}
.dotted-spaced {
background-image: linear-gradient(to right, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: top;
background-size: 10px 1px;
background-repeat: repeat-x;
}
.left {
float: left;
padding: 40px 10px;
background-color: #F0F0DA;
}
.left.dotted {
border-left: 1px #333 dotted;
border-top: none;
}
.left.dotted-gradient {
background-image: linear-gradient(to bottom, #333 40%, rgba(255, 255, 255, 0) 20%);
background-position: left;
background-size: 1px 3px;
background-repeat: repeat-y;
}
.left.dotted-spaced {
background-image: linear-gradient(to bottom, #333 10%, rgba(255, 255, 255, 0) 0%);
background-position: left;
background-size: 1px 10px;
background-repeat: repeat-y;
}

Here's a trick I've used on a recent project to achieve nearly anything I want with horizontal borders. I use <hr/> each time I need an horizontal border. The basic way to add a border to this hr is something like
hr {border-bottom: 1px dotted #000;}
But if you want to take control of the border and, for example increase, the space between dots, you may try something like this:
hr {
height:14px; /* specify a height for this hr */
overflow:hidden;
}
And in the following, you create your border (here's an example with dots)
hr:after {
content:".......................................................................";
letter-spacing: 4px; /* Use letter-spacing to increase space between dots*/
}
This also means that you can add text-shadow to the dots, gradients etc. Anything you want...
Well, it works really great for horizontal borders. If you need vertical ones, you may specify a class for another hr and use the CSS3 rotation property.
You cannot do it with pure CSS - the CSS3 spec even has a specific quote about this:
Note: There is no control over the spacing of the dots and dashes, nor over the length of the dashes. Implementations are encouraged to choose a spacing that makes the corners symmetrical.
You can, however, use either a border-image or a background image that does the trick.
This uses the standard CSS border and a pseudo element+overflow:hidden.
In the example you get three different 2px dashed borders: normal, spaced like a 5px, spaced like a 10px. Is actually 10px with only 10-8=2px visible.
div.two{border:2px dashed #FF0000}
div.five:before {
content: "";
position: absolute;
border: 5px dashed #FF0000;
top: -3px;
bottom: -3px;
left: -3px;
right: -3px;
}
div.ten:before {
content: "";
position: absolute;
border: 10px dashed #FF0000;
top: -8px;
bottom: -8px;
left: -8px;
right: -8px;
}
div.odd:before {left:0;right:0;border-radius:60px}
div {
overflow: hidden;
position: relative;
text-align:center;
padding:10px;
margin-bottom:20px;
}
<div class="two">Kupo nuts here</div>
<div class="five">Kupo nuts<br/>here</div>
<div class="ten">Kupo<br/>nuts<br/>here</div>
<div class="ten odd">Kupo<br/>nuts<br/>here</div>
Applied to small elements with big rounded corners may make for some fun effects.
So starting with the answer given and applying the fact that CSS3 allows multiple settings - the below code is useful for creating a complete box:
#border {
width: 200px;
height: 100px;
background: yellow;
text-align: center;
line-height: 100px;
background: linear-gradient(to right, orange 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(blue 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(to right, green 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(red 50%, rgba(255, 255, 255, 0) 0%);
background-position: top, right, bottom, left;
background-repeat: repeat-x, repeat-y;
background-size: 10px 1px, 1px 10px;
}
<div id="border">
bordered area
</div>
Its worth noting that the 10px in the background size gives the area that the dash and gap will cover. The 50% of the background tag is how wide the dash actually is. It is therefore possible to have different length dashes on each border side.
Late to the party but I found that neat little tool online.
https://kovart.github.io/dashed-border-generator/
See the MDN docs for the available values for border-style:
none : No border, sets width to 0.
This is the default value.
hidden : Same as 'none', except in terms of
border conflict resolution for table
elements.
dashed : Series of short
dashes or line segments.
dotted :
Series of dots.
double : Two straight
lines that add up to the pixel amount
defined as border-width.
groove :
Carved effect.
inset : Makes the box
appear embedded.
outset : Opposite of
'inset'. Makes the box appear 3D
(embossed).
ridge : Opposite of
'groove'. The border appears 3D
(coming out).
solid : Single,
straight, solid line.
Apart from those choices, there is no way to influence the standard border's style.
If the possibilities there are not to your liking, you could use CSS3's border-image but note that browser support for this is still very spotty (EDIT: browser support is good as of 2020).
This is an old, but still very relevant topic. The current top answer works well, but only for very small dots. As Bhojendra Rauniyar already pointed out in the comments, for larger (>2px) dots, the dots appear square, not round. I found this page searching for spaced dots, not spaced squares (or even dashes, as some answers here use).
Building on this, I used radial-gradient. Also, using the answer from Ukuser32, the dot-properties can easily be repeated for all four borders. Only the corners are not perfect.
div {
padding: 1em;
background-image:
radial-gradient(circle at 2.5px, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle at 2.5px, #000 1.25px, rgba(255,255,255,0) 2.5px),
radial-gradient(circle, #000 1.25px, rgba(255,255,255,0) 2.5px);
background-position: top, right, bottom, left;
background-size: 15px 5px, 5px 15px;
background-repeat: repeat-x, repeat-y;
}
<div>Some content with round, spaced dots as border</div>
The radial-gradient expects:
the shape and optional position
two or more stops: a color and radius
Here, I wanted a 5 pixel diameter (2.5px radius) dot, with 2 times the diameter (10px) between the dots, adding up to 15px. The background-size should match these.
The two stops are defined such that the dot is nice and smooth: solid black for half the radius and than a gradient to the full radius.
Building 4 edges solution basing on #Eagorajose's answer with shorthand syntax:
background: linear-gradient(to right, #000 33%, #fff 0%) top/10px 1px repeat-x, /* top */
linear-gradient(#000 33%, #fff 0%) right/1px 10px repeat-y, /* right */
linear-gradient(to right, #000 33%, #fff 0%) bottom/10px 1px repeat-x, /* bottom */
linear-gradient(#000 33%, #fff 0%) left/1px 10px repeat-y; /* left */
#page {
background: linear-gradient(to right, #000 33%, #fff 0%) top/10px 1px repeat-x, /* top */
linear-gradient(#000 33%, #fff 0%) right/1px 10px repeat-y, /* right */
linear-gradient(to right, #000 33%, #fff 0%) bottom/10px 1px repeat-x, /* bottom */
linear-gradient(#000 33%, #fff 0%) left/1px 10px repeat-y; /* left */
width: 100px;
height: 100px;
}
<div id="page"></div>
This is a really old question but it has a high ranking in Google so I'm going to throw in my method which could work depending on your needs.
In my case, I wanted a thick dashed border that had a minimal break in between dashes. I used a CSS pattern generator (like this one: http://www.patternify.com/) to create a 10px wide by 1px tall pattern. 9px of that is solid dash color, 1px is white.
In my CSS, I included that pattern as the background image, and then scaled it up by using the background-size attribute. I ended up with a 20px by 2px repeated dash, 18px of that being solid line and 2px white. You could scale it up even more for a really thick dashed line.
The nice thing is since the image is encoded as data you don't have the additional outside HTTP request, so there's no performance burden. I stored my image as a SASS variable so I could reuse it in my site.
So many people are say "You can't". Yes you can. It's true that there is not a css rule to control the gutter space between the dashes but css has other abilities. Don't be so quick to say that a thing can not be done.
.hr {
border-top: 5px dashed #CFCBCC;
margin: 30px 0;
position: relative;
}
.hr:before {
background-color: #FFFFFF;
content: "";
height: 10px;
position: absolute;
top: -2px;
width: 100%;
}
.hr:after {
background-color: #FFFFFF;
content: "";
height: 10px;
position: absolute;
top: -13px;
width: 100%;
}
Basically the border-top height (5px in this case) is the rule that determines the gutter "width". OIf course you would need to adjust the colors to match your needs. This also is a small example for a horizontal line, use left and right to make the vertical line.
In my case I needed curved corners and thin border so I came up with this solution:
/* For showing dependencies between attributes */
:root {
--border-width: 1px;
--border-radius: 4px;
--bg-color: #fff;
}
/* Required: */
.dropzone {
position: relative;
border: var(--border-width) solid transparent;
border-radius: var(--border-radius);
background-clip: padding-box;
background-color: var(--bg-color);
}
.dropzone::before {
content: '';
position: absolute;
top: calc(var(--border-width) * -1); /* or without variables: 'top: -1px;' */
right: calc(var(--border-width) * -1);
bottom: calc(var(--border-width) * -1);
left: calc(var(--border-width) * -1);
z-index: -1;
background-image: repeating-linear-gradient(135deg, transparent 0 8px, var(--bg-color) 8px 16px);
border-radius: var(--border-radius);
background-color: rgba(0, 0, 0, 0.38);
}
/* Optional: */
html {
background-color: #fafafb;
display: flex;
justify-content: center;
}
.dropzone {
box-sizing: border-box;
height: 168px;
padding: 16px;
display: flex;
align-items: center;
justify-content: center;
cursor: pointer;
}
.dropzone::before {
transition: background-color 0.2s ease-in-out;
}
.dropzone:hover::before {
background-color: rgba(0, 0, 0, 0.87);
}
<div class='dropzone'>

The idea is to put svg pattern behind element and display only thin line of this pattern as element border.
Short answer: You can't.
You will have to use border-image property and a few images.
IF you're only targeting modern browsers, AND you can have your border on a separate element from your content, then you can use the CSS scale transform to get a larger dot or dash:
border: 1px dashed black;
border-radius: 10px;
-webkit-transform: scale(8);
transform: scale(8);
It takes a lot of positional tweaking to get it to line up, but it works. By changing the thickness of the border, the starting size and the scale factor, you can get to just about thickness-length ratio you want. Only thing you can't touch is dash-to-gap ratio.

I made a javascript function to create dots with an svg. You can adjust dot spacing and size in the javascript code.
var make_dotted_borders = function() {

You could create a canvas (via javascript) and draw a dotted line within. Within the canvas you can control how long the dash and the space in between shall be.
We needed to have circles and this is how we solved it :)
More or less this is done to the element where the styled "border" is needed:
:before {
position: absolute;
width: 100%;
height: 10px;
top:0;
left: 0;

Here's a solution using CSS only with the use of a clip-path to mask the excess border. Unlike the most voted answer this allows for transparent backgrounds. You can also use get rounded borders by matching the clip-path round property to the border-radius.
.demo {
display: inline-flex;
width: 200px;
height: 100px;
position: relative;
clip-path: inset(0 round 30px 0 30px 0);
}
.demo::before {
content: '';
position: absolute;
left: -7px;
top: -7px;
right: -7px;
bottom: -7px;
border: 8px dashed rgba(0, 0, 255, 0.3);
border-radius: 37px 0 37px 0;
box-sizing: border-box;
}
<div class="demo"></div>
Here's a sass mixin for those interested
=dashed-border($size: 5px, $thickness: 1px, $color: black, $round: 0px)
$corners: ''
#for $i from 1 through length($round)
$value: nth($round, $i)
#if $value != 0
$corners: unquote($corners + calc(#{$value} - #{$size}) + ' ')
#else
$corners: unquote($corners + #{$value} + ' ')
clip-path: inset(0 round $corners)
&::before
content: ''
position: absolute
left: - $size + $thickness
top: - $size + $thickness
right: - $size + $thickness
bottom: - $size + $thickness
border: $size dashed $color
border-radius: $round
box-sizing: border-box
AFAIK there isn't a way to do this. You could use a dashed border or perhaps increase the width of the border a bit, but just getting more spaced out dots is impossible with CSS.
