Thank you in advance for your help.
I have spent a good deal of time scouring the web and this forum for a solution to having a diagonal angled bottom to my navigation buttons. Here is an example:
I want to avoid using images if possible. I'm wondering how to create a box like this in the example image for each navigation choice with CSS. This navigation code will make its way into a Wordpress install. I really appreciate the expertise. Thank you again!
So good-news, bad-news...
This can be most-of-the-way done using nothing but CSS.
For sufficiently-new browsers (ie: you don't require IE<=8 to maintain all styles that Chrome 42 has) this can be done without using extra DOM elements.
This can also be done using just CSS ...wait for it...
buuuut the CSS-only version can only make the angle a set width.
It can't make the angle stretch across an arbitrary width, so either the buttons have to be the same length, or the width/height of the angle has to be the same on all buttons (meaning part of the bottom will be flat, on longer buttons).
CSS-only Solution (good enough?)
nav {
background-color: green;
padding: 20px;
}
nav > button {
background-color: rgb(60, 60, 60);
color: rgb(120, 120, 120);
position: relative;
border-radius: none;
border: none;
padding: 20px;
}
nav > button:after {
content: "";
width: 0;
height: 0;
right: 0;
bottom: 0;
position: absolute;
border-left: 60px solid transparent;
border-bottom: 15px solid blue;
}
<nav >
<button >About</button>
<button >Bios</button>
</nav>
I made the colours obvious for a reason.
For the full experience of the cheat, I'll make the solution a little more obvious, by changing the colour of the left border:
Behind the Scenes Look
nav {
background-color: green;
padding: 20px;
}
nav > button {
background-color: rgb(60, 60, 60);
color: rgb(120, 120, 120);
position: relative;
border-radius: none;
border: none;
padding: 20px;
}
nav > button:after {
content: "";
width: 0;
height: 0;
right: 0;
bottom: 0;
position: absolute;
border-left: 60px solid red;
border-bottom: 15px solid blue;
}
<nav >
<button >About</button>
<button >Bios</button>
</nav>
As you can see, the triangle that I created using the border-bottom (in blue) and border-left (transparent) is just about perfect.
The width of the border-left determines the width of this effect, and the height of the border-bottom determines the height; it just happens that the left one is invisible.
If that blue were set to the same green as the <nav> itself, then it would look like a notch was missing from the button, rather than having a corner painted over.
If you wanted to make this ES6-8 friendly, you'd just add 1 div per button (after each button or whatever), and size that and use its borders.
Really, you'd need to add a div to contain the div and the button, as well (so the container was relatively positioned, the button took up 100% of its space, and the paint-chip was absolutely positioned inside).
If you don't care about old browsers getting the exact same view, you really don't need to do this to yourself.
That's most of the way solved...
If you can say "My theme's smallest button is 60px, so a 60px triangle is okay", then great. Change the colours and you're done.
If not, there's a little more you can do.
It's not ideal, and it's not as pretty as it could be (still prettier than a lot out there), but if you can use JS to do this, and you can guarantee that all of the buttons are going to be on the page before the code runs, and their widths won't change, you can do something like:
JS + CSS (good enough!)
(function () {
var nav;
var buttons;
var style;
var styleText;
function getElWidth (el) { return el.getBoundingClientRect().width; }
function borderLeftText (width, i) {
return ["nav > button:nth-child(", i + 1, "):after { border-left: ", width, "px solid transparent; }"].join("");
}
function getStyleEntries (els) {
return els.map(getElWidth).map(borderLeftText);
}
try {
nav = document.querySelector("nav");
buttons = [].slice.call(nav.querySelectorAll("button"));
style = document.createElement("style");
styleText = getStyleEntries(buttons).join("\n");
style.textContent = styleText;
document.head.appendChild(style);
}
catch (err) {
// because the same browsers that will blow up won't support the CSS anyway;
// don't fix it, just move on
// good code shouldn't do this, but that's another story
}
}());
nav {
background-color: green;
padding: 20px;
}
nav > button {
background-color: rgb(60, 60, 60);
color: rgb(120, 120, 120);
position: relative;
border-radius: none;
border: none;
padding: 20px;
}
nav > button:after {
content: "";
width: 0;
height: 0;
right: 0;
bottom: 0;
position: absolute;
border-left: 60px solid transparent;
border-bottom: 15px solid green;
}
<nav >
<button >About</button>
<button >Bios</button>
</nav>
Here I'm basically grabbing all buttons that exist at this time, and writing my own CSS file, full of
nav > button:nth-child(1):after { /*...*/ }
nav > button:nth-child(2):after { /*...*/ }
and then appending a <style> tag to the <head> with that text inside.
There will just be one rule inside each one of those selectors; the border-left width is going to be set to the actual width of the button, in pixels.
Terms and Conditions
Now you have exactly what you wanted, but it required JS and requires that the buttons be on the page before that code runs, and requires that the widths not change (through styling, or through media-queries, et cetera). If either of those things happens, and you want to keep the corners updated, that code needs to be run again.
And if that's the case, special care should be made to cache and reuse the style tag, so that you don't have 8 tags with the same rules, on the page.
Conclusion
If you're good with mostly-fine, go CSS-only.
If you're good with knowing that the fix doesn't have to respond in real-time, or be applied to more and more buttons that are dynamically added, go JS + CSS.
If neither of those is good enough, use an .svg or .png
Transform: skewY(deg);
will skew a div up like that, you might need to build it in layers though, and then skew the text -deg to unskew the text
Simple example:
https://jsfiddle.net/uex2umac/
.wrapper{
width:500px;
height:300px;
background-color:#000;
overflow:hidden;
}
.tobeskew{
width:280px;
height:220px;
margin-bottom:0px;
background-color:#f1f;
text-align:center;
transform:skewY(-15deg);
}
p{
transform:skewY(15deg);
line-height:220px;
font-size:40px;
color:#fff;
}
<Div class="wrapper">
<div class="tobeskew">
<p>Hello</p>
</div>
</div>
Here's a solution using SVG background images. Note that using SVG requires IE9+ though...
BODY
{
background-color: #333;
}
.button
{
float:left;
float: left;
font-family: sans-serif;
font-weight: bold;
font-size: 44px;
background-image: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 115' preserveAspectRatio='none'><polygon points='0 0 100 0 100 100 0 115' fill='%23282828'/></svg>");
background-size: 100% 100%;
color: #999;
height: 110px;
line-height: 96px;
padding: 0 50px;
margin-right: 10px;
}
.button.selected
{
color: #fbac31;
background-image: url("data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 100 115' preserveAspectRatio='none'><polygon points='0 0 100 0 100 100 0 115' fill='black'/></svg>");
}
<div class="button">
<div>ABOUT</div>
</div>
<div class="button selected">
<div>BIOS</div>
</div>
I have a weird problem and honestly I have no idea how to do that.
I have a box with background image. Over the background image I have a lot of boxes with a background color and text. I would like the color of the text in every box to be transparent, so the color will be the part of the background image that text is above.
Here is an example: http://jsfiddle.net/wjdwohdd/5/
Instead of the green background, it should be an image.
<div class="box">
<div class="background">
Example text
</div>
</div>
.box {
width:200px;
height:20px;
background-color: green;
padding: 10px;
}
.background {
color: transparent;
height: 100%;
width: auto;
background-color: red;
text-align: center;
}
If I set color: transparent, the text's color becomes red and I am not sure even if it is possible to be the background image.
EDIT: I updated my jsfiddle. I would like the color of the text to be the part of the image that is behind the text.
You can do that, but you need a pretty new property: mix-blend-mode.
Even though it, support is growing: it has been supported in FF for a while, and it is supported in the latest Chrome.
To get it, you need a gray text on a red background, and set the mode to hard-light
body {
background-image: url(http://placekitten.com/1200/800);
}
.test {
font-size: 300px;
color: #888;
background-color: red;
mix-blend-mode: hard-light;
}
<div class="test">TESTING</div>
i would suggest to use a color for the font in the parent element and then in the child element inherit the font color, not sure what you really want
.box {
width:200px;
height:20px;
background-color: green;
padding: 10px;
color: blue;
}
.background {
color: inherit;
height: 100%;
width: auto;
background-color: red;
text-align: center;
}
otherwise use a rgb color for the font in the child element with a transparency then your background will be visible for example something like color: rgba(0, 0, 0, 0.5);
I dont know whether it is possible to do using CSS. Only solution that I can come up with is using Canvas. But it is too complicated and lot of coding. back canvas contains the image that you want to show and in front canvas you do background coloring and letter writing. Here goes the code:
HTML
<body>
<canvas id="back">
</canvas>
<canvas id="front">
</canvas>
</body>
CSS
#back{
position: fixed;
top: 40px;
left: 40px;
z-index: -1;
}
#front{
position: fixed;
top: 60px;
left: 60px;
z-index: 99;
}
JavaScript
window.onload = function(){
var h = new Image();
h.src = 'images/color.jpg';
var back = document.getElementById('back');
back.width = h.width;
back.height = h.height;
back.getContext('2d').drawImage(h,0,0,h.width,h.height);
var front = document.getElementById('front');
var back = document.getElementById('back');
front.width = h.width - 40;
front.height = h.height - 40;
var ctx = front.getContext('2d');
ctx.fillStyle="#ED6";
ctx.fillRect(0,0,h.width - 40,h.height - 40);
ctx.font="150px Verdana";
ctx.fillStyle= 'rgba(0,0,0,1)';
ctx.fillText("HELLO" , h.width/2 - 300 , h.height/2 - 25);
maketransparent(front,back);
};
function maketransparent(front,back){
var backimage = back.getContext('2d').getImageData(0,0,back.width,back.height);
var frontimage = front.getContext('2d').getImageData(0,0,front.width,front.height);
for(var i=0; i<frontimage.data.length; i=i+4){
var line=Math.floor(i/(4*front.width));
line=line+20;
var backi=(line*back.width*4) + 80 + (i%(front.width*4));
if(frontimage.data[i]+frontimage.data[i+1]+frontimage.data[i+2]<50){
frontimage.data[i]=backimage.data[backi];
frontimage.data[i+1]=backimage.data[backi+1];
frontimage.data[i+2]=backimage.data[backi+2];
}
}
front.getContext('2d').putImageData(frontimage,0,0);
}
I hope this is the right place to post.
I am a a full stack dev with a focus on the backend for the last few years so I am trying to make sure I am approaching this the right way and that there isn't a newer way to do this then my proposed solution below:
See the attached screen shot. This is the main nav for a freelance project I took on. It is not a problem on the pages without a hero image, but where there is a hero, I need the image to be masked as shown. If you can't see it, the selected nav item has a triangle underneath it that is attached to a 2px red line that extends the width of the screen. This triangle is made by this same 2px red line and if there is a hero image, the top of the image is masked by this red line and some white space (about 8 pixels) equal to the height of the triangle.
My Proposed Solution
I was going to have the designer prepare a graphic for me that is a long png, about 3000 by 8, the only transparency being the part underneath the triangle. When the page loads I was going to load the graphic and position it absolutely underneath the selected nav item with JS, masking the image beneath it.
My Question
Is there a better way to achieve this in 2015 - ie clip paths? Is there a good tutorial on the subject - everything I see is for more elaborate things that don't involve added graphics (ie the red line and white mask at the top.
The Effect
EDIT
This is the js I will use to get the proper offset for my lo-fi (2011ish) solution, observant devs will notice the wordpress generated classes:
<script type="text/javascript">
var x = $("#main-nav .current-menu-item a").offset().left;
var y = $("#main-nav .current-menu-item a").offset().top;
var w = $("#main-nav .current-menu-item a").width();
var cx = (x + w / 2);
//get target width and set x offset
tw = $("#masking-selection").width()
tx = cx - (tw/2)
//move the masking item
$("#masking-selection").offset({top: (y+20), left: tx })
</script>
Hope I understand your question. Below is one way to achieve your need.
Note: Adjust to suit your need.

I'm trying to create horizontal navigation bar, that fills out the screen, or parent container and will have equal horizontal padding for elements, that will equally reduce on smaller window width. Using display:table-cell I have got to the point that it nicely reduces but is not equal. Longer titles have more padding. I'm open to any working solutions, ideally css but if that is not possible, than anything that will work without glitches. What i have so far can be seen here
ul {
list-style:none;
padding:0;
width:100%;
display:table;
border-top:1px solid;
border-bottom:1px solid;
border-left:1px solid
}
li {
border-right: 1px solid;
margin:0;
display:table-cell;
position:relative;
text-align:center
}
<ul>
<li>some title</li>
<li>some longer title</li>
<li>some title</li>
</ul>
http://jsfiddle.net/xZ6q3/16/
Solved it (and learned a lot). The basic idea is to run through all list items and calculate the average padding. Then run through them again and set their width to their text width + average padding.
Heres the updated jsfiddle: http://jsfiddle.net/xZ6q3/21/
// calculate the average padding
var totalPadding = 0;
var count = 0;
$('li').each(function(){
var t = $(this);
var outer = t.outerWidth(true);
var inner = t.textWidth();
var padding = outer - inner;
totalPadding += outer - inner;
count++;
});
totalPadding /= count;
// set each width to text width + average padding
$('li').each(function(){
var t = $(this);
var inner = t.textWidth();
var newWidth = inner + totalPadding;
t.css('width', newWidth);
});
To make it work, I had to use Phil's textWidth() and listen to window resize events. See the jsFiddle.
Try this
ul {
border-bottom: 1px solid;
border-left: 1px solid;
border-top: 1px solid;
display: inline-block;
list-style: none outside none;
padding: 0;
}
li {
border-right: 1px solid;
display: inline-block;
margin: 0;
padding: 0 17px;
position: relative;
text-align: center;
}
First, I would go for float:left property and then change values for different screen resolutions.
ul li {
float:left;
padding-left: 15px;
padding-right: 15px;
}
#media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
ul li {
padding-left: 5px;
padding-right: 5px;
}
}
Is there any way of getting rounded corners on the outline of a div element, similar to border-radius?
I had an input field with rounded border and wanted to change colour of focus outline. I couldn't tame the horrid square outline to the input control.
So instead, I used box-shadow. I actually preferred the smooth look of the shadow, but the shadow can be hardened to simulate a rounded outline:
input, input:focus {
border: none;
border-radius: 2pt;
box-shadow: 0 0 0 1pt grey;
outline: none;
transition: .1s;
}
/* Smooth outline with box-shadow: */
.text1:focus {
box-shadow: 0 0 3pt 2pt cornflowerblue;
}
/* Hard "outline" with box-shadow: */
.text2:focus {
box-shadow: 0 0 0 2pt red;
}
<input class="text1">
<br>
<br>
<input type=text class="text2">
I usually accomplish this using the :after pseudo-element:
of course it depends on usage, this method allows control over individual borders, rather than using the hard shadow method.
you could also set -1px offsets and use a background linear gradient (no border) for a different effect once again.
body {
margin: 20px;
}
a {
background: #999;
padding: 10px 20px;
border-radius: 5px;
text-decoration: none;
color: #fff;
position: relative;
border: 2px solid #000;
}
a:after {
content: '';
display: block;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
border-radius: 5px;
border: 2px solid #ccc;
}
Button
Similar to Lea Hayes above, but here's how I did it:
div {
background: #999;
height: 100px;
width: 200px;
border: #999 solid 1px;
border-radius: 10px;
margin: 15px;
box-shadow: 0px 0px 0px 1px #fff inset;
}
<div></div>
No nesting of DIVs or jQuery necessary, Altho for brevity I have left out the -moz and -webkit variants of some of the CSS. You can see the result above
Use this one:
box-shadow: 0px 0px 0px 1px red;
I wanted some nice focus accessibility for dropdown menus in a Bootstrap navbar, and was pretty happy with this:
a.dropdown-toggle:focus {
display: inline-block;
box-shadow: 0 0 0 2px #88b8ff;
border-radius: 2px;
}
Visit Stackoverflow
We may see our wishes soonish by setting outline-style: auto It's on WebKits radar: http://trac.webkit.org/changeset/198062/webkit
See ya in 2030.
You're looking for something like this, I think.
div {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
Edit
There is a Firefox-only -moz-outline-radius properly, but that won't work on IE/Chrome/Safari/Opera/etc. So, it looks like the most cross-browser-compatible way* to get a curved line around a border is to use a wrapper div:
div.inner {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid black;
background-color: #CCC;
height: 100px;
width: 160px;
}
div.outer {
display: inline-block;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;
border: 1px solid red;
}
<div class="outer">
<div class="inner"></div>
</div>
*aside from using images
Firefox 88+: border-radius
From April 2021 you will be able to use a simple CSS for Firefox:
.actual {
outline: solid red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In Firefox 88+,
<span class="actual">this outline</span>
should look like
<span class="expected">this border</span>
Current behaviour in Firefox 86.0:
Webkit: no solution
Using outline-style: auto will tell the «user agent to render a custom outline style»: see [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/outline-style(.
Webkit-based browsers will then draw the outline over the border, when you use outline-style: auto. It's difficult to style it properly.
.actual {
outline: auto red;
border-radius: 10px;
}
.expected {
border: solid red;
border-radius: 10px;
}
In WebKit browsers (Chrome, Edge),
<span class="actual">this outline</span>
should look close to
<span class="expected">this border</span>
Current behaviour in Chrome 89.0:
More information
From Firefox 88 (to be released April 20 2021), outline will follow the shape of border-radius.
The current -moz-outline-radius will become redundant and will be removed.
See MDN's entry about -moz-outline-radius:
From Firefox 88 onwards, the standard outline property will follow the shape of border-radius, making -moz-outline-radius properties redundant. As such, this property will be removed.
(Feb 2023)
As far as I know, the Outline radius is only supported by Firefox and Firefox for android.
-moz-outline-radius: 1em;
I just found a great solution for this, and after looking at all the responses so far, I haven't seen it posted yet. So, here's what I did:
I created a CSS Rule for the class and used a pseudo-class of :focus for that rule. I set outline: none to get rid of that default light-blue non-border-radius-able 'outline' that Chrome uses by default. Then, in that same :focus pseudo-class, where that outline no longer exists, I added my radius and border properties. Leading to the following
outline: none;
border-radius: 5px;
border: 2px solid maroon;
to have a maroon-colored outline with a border radius that now appears when the element is tab-selected by the user.
If you want to get an embossed look you could do something like the following:
.embossed {
background: #e5e5e5;
height: 100px;
width: 200px;
border: #FFFFFF solid 1px;
outline: #d0d0d0 solid 1px;
margin: 15px;
}
.border-radius {
border-radius: 20px 20px 20px 20px;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
-khtml-border-radius: 20px;
}
.outline-radius {
-moz-outline-radius: 21px;
}
<div class="embossed"></div>
<div class="embossed border-radius"></div>
<div class="embossed border-radius outline-radius">-MOZ ONLY</div>
I have not found a work around to have this work in other browsers.
EDIT: The only other way you can do this is to use box-shadow, but then this wont work if you already have a box shadow on that element.
Chrome 94.0+
I tested it in chrome 94.0 and it seems that the outline property honors the border-radius now.
.outline {
outline: 2px solid red;
}
.border {
border: 2px solid red;
}
.outline-10 {
border-radius: 10px;
}
.border-2 {
border-radius: 2px;
}
.outline-2 {
border-radius: 2px;
}
.border-10 {
border-radius: 10px;
}
.outline-50 {
border-radius: 50%;
}
.border-50 {
border-radius: 50%;
}
.circle {
display: inline-block;
width:50px;
height: 50px;
}

As others have said, only firefox supports this. Here is a work around that does the same thing, and even works with dashed outlines.
.has-outline {
display: inline-block;
background: #51ab9f;
border-radius: 10px;
padding: 5px;
position: relative;
}
.has-outline:after {
border-radius: 10px;
padding: 5px;
border: 2px dashed #9dd5cf;
position: absolute;
content: '';
top: -2px;
left: -2px;
bottom: -2px;
right: -2px;
}
<div class="has-outline">
I can haz outline
</div>
No. Borders sit on the outside of the element and on the inside of the box-model margin area. Outlines sit on the inside of the element and the box-model padding area ignores it. It isn't intended for aesthetics. It's just to show the designer the outlines of the elements. In the early stages of developing an html document for example, a developer might need to quickly discern if they have put all of the skeletal divs in the correct place. Later on they may need to check if various buttons and forms are the correct number of pixels apart from each other.
Borders are aesthetic in nature. Unlike outlines they are actually apart of the box-model, which means they do not overlap text set to margin: 0; and each side of the border can be styled individually.
If you're trying to apply a corner radius to outline I assume you are using it the way most people use border. So if you don't mind me asking, what property of outline makes it desirable over border?
COMBINING BOX SHADOW AND OUTLINE.
A slight twist on Lea Hayes answer
I found
input[type=text]:focus {
box-shadow: 0 0 0 1pt red;
outline-width: 1px;
outline-color: red;
}
gets a really nice clean finish. No jumping in size which you get when using border-radius
There is the solution if you need only outline without border. It's not mine. I got if from Bootstrap css file. If you specify outline: 1px auto certain_color, you'll get thin outer line around div of certain color. In this case the specified width has no matter, even if you specify 10 px width, anyway it will be thin line. The key word in mentioned rule is "auto".
If you need outline with rounded corners and certain width, you may add css rule on border with needed width and same color. It makes outline thicker.
I was making custom radio buttons and the best customisable way i've found is using pseudo elements like this: Codepen
/*CSS is compiled from SCSS*/
.product-colors {
margin-bottom: 1em;
display: flex;
align-items: center;
}
.product-colors label {
position: relative;
width: 2.1em;
height: 2.1em;
margin-right: 0.8em;
cursor: pointer;
}
.product-colors label:before {
opacity: 0;
width: inherit;
height: inherit;
padding: 2px;
border: 2px solid red;
border-radius: 0.2em;
content: "";
position: absolute;
z-index: 1;
background: transparent;
top: -4px;
left: -4px;
}
.product-colors input {
position: absolute;
opacity: 0;
width: 0;
height: 0;
}
.product-colors input:checked + label:before, .product-colors input:focus + label:before {
opacity: 1;
}
<div class="product-colors">
<input type="radio" name="cs" id="cs1" value="black">
<label for="cs1" style="background:black"></label>
<input type="radio" name="cs" id="cs2" value="green">
<label for="cs2" style="background:green"></label>
<input type="radio" name="cs" id="cs3" value="blue">
<label for="cs3" style="background:blue"></label>
<input type="radio" name="cs" id="cs4" value="yellow">
<label for="cs4" style="background:yellow"></label>
</div>
clip-path: circle(100px at center);
This will actually make clickable only circle, while border-radius still makes a square, but looks as circle.
The simple answer to the basic question is no. The only cross-browser option is to create a hack that accomplishes what you want. This approach does carry with it certain potential issues when it comes to styling pre-existing content, but it provides for more customization of the outline (offset, width, line style) than many of the other solutions.
On a basic level, consider the following static example (run the snippent for demo):
.outline {
border: 2px dotted transparent;
border-radius: 5px;
display: inline-block;
padding: 2px;
margin: -4px;
}
/* :focus-within does not work in Edge or IE */
.outline:focus-within, .outline.edge {
border-color: blue;
}
br {
margin-bottom: 0.75rem;
}
<h3>Javascript-Free Demo</h3>
<div class="outline edge"><input type="text" placeholder="I always have an outline"/></div><br><div class="outline"><input type="text" placeholder="I have an outline when focused"/></div> *<i>Doesn't work in Edge or IE</i><br><input type="text" placeholder="I have never have an outline" />
<p>Note that the outline does not increase the spacing between the outlined input and other elements around it. The margin (-4px) compensates for the space that the outlines padding (-2px) and width (2px) take up, a total of 4px.</p>
Now, on a more advanced level, it would be possible to use JavaScript to bootstrap elements of a given type or class so that they are wrapped inside a div that simulates an outline on page load. Furthermore, event bindings could be established to show or hide the outline on user interactions like this (run the snippet below or open in JSFiddle):
h3 {
margin: 0;
}
div {
box-sizing: border-box;
}
.flex {
display: flex;
}
.clickable {
cursor: pointer;
}
.box {
background: red;
border: 1px solid black;
border-radius: 10px;
height: 5rem;
display: flex;
align-items: center;
text-align: center;
color: white;
font-weight: bold;
padding: 0.5rem;
margin: 1rem;
}

In closing, let me reiterate, that implementing this approach may require more styling than what I have included in my demos, especially if you have already styled the element you want outlined.
outline-style: auto has had full browser support for ages now.
Shorthand is:
outline: auto blue;
This let's you set a custom color, but not a custom thickness, unfortunately (although I think the browser default thickness is a good default).
You can also set a custom outline-offset when using outline-style: auto.
outline: auto blue;
outline-offset: 0px;
you can use box-shadow instead of outline like this
box-shadow: 0 0 1px #000000;
border-radius: 50px;
outline: none;
Try using padding and a background color for the border, then a border for the outline:
.round_outline {
padding: 8px;
background-color: white;
border-radius: 50%;
border: 1px solid black;
}
Worked in my case.
I just set outline transparent.
input[type=text] {
outline: rgba(0, 0, 0, 0);
border-radius: 10px;
}
input[type=text]:focus {
border-color: #0079ff;
}
I like this way.
.circle:before {
content: "";
width: 14px;
height: 14px;
border: 3px solid #fff;
background-color: #ced4da;
border-radius: 7px;
display: inline-block;
margin-bottom: -2px;
margin-right: 7px;
box-shadow: 0px 0px 0px 1px #ced4da;
}
It will create gray circle with wit border around it and again 1px around border!
