How to make this shape in CSS? - html

Is it possible to make this shape in CSS3?

You can do something like this, using a pseudo selector of after.

CSS
div {
height: 200px;
background: blue;
position: relative;
width: 400px;
}
div:after {
content: '';
position: absolute;
top: -50px;
left: -200px;
border-top: 300px solid white;
border-left: 300px solid white;
width: 0;
background: #fff;

Display Pseudo element above parent when parent's overflown is hidden

div {
margin: 50px;
position: relative;
background-color: red;
width: 200px;
height: 50px;
border: 2px solid black;
}
div::after {
content: '';
position: absolute;
background-color: green;
width: 100px;
height: 100px;
border-radius: 100%;
top: -25px;
left:50px;
border: 2px solid black;
}
div.overflow-hidden {
overflow: hidden;
}
<div>1st</div>
<div class="overflow-hidden">2nd</div>
1st case: as expected.
2nd case[overflow-hidden]: Middle part of top and bottom border should be green. Looks like circle is not above its parent div's border. Is there any way to make it above it? Whats happening here? Will the z-index work?
Why is this happening?
This is because overflow: hidden; clips the content to the content box.
hidden
Content is clipped if necessary to fit the content box. No scrollbars
are provided.
MDN Web docs - https://developer.mozilla.org/en/docs/Web/CSS/overflow
This can be seen in the first example below as I have changed the border to be transparent.
What can you do?
One way to get around this would be to apply the border using an absolutely positioned pseudo element instead of to the containing div.
div {
background-color: red;
height: 50px;
margin: 50px;
overflow: hidden;
position: relative;
width: 200px;
}
div::after {
background-color: green;
border: 2px solid black;
border-radius: 100%;
content: '';
height: 100px;
left: 50px;
position: absolute;
top: -25px;
width: 100px;
}
div.overflow-with-border {
border: 2px solid transparent;
}
div.overflow-with-pseudo {
padding: 2px;
}
div.overflow-with-pseudo::before {
border: 2px solid black;
box-sizing: border-box;
content: '';
height: 100%;
left: 0;
position: absolute;
top: 0;
width: 100%;
}
<div class="overflow-with-border">1st</div>
<div class="overflow-with-pseudo">2nd</div>

Add a second element to div with :after

Hi I've got follow div:
.box {
width: 100px;
height: 20px;
border: 1px solid black;
}
.box:after {
content: '';
width: 20px;
height: 20px;
background-color: blue;
}
<div class="box"></div>
I would like to add a second div to the .box with pseudo class after. I thought it would work like this, but nothing happens. It should look like this:
How to do this with after?
Thanks.
Try This
.box {
width: 100px;
height: 20px;
border: 1px solid black;
}
.box:after {
content: '';
width: 20px;
height: 20px;
background-color: blue;
display:block;
float:right;
}
<div class="box"></div>
You're code is right, the only thing missing is the property display to that element. Just add a display: block on the :after element. To easily manipulate the pseudo-element, make the main element position: relative, then the :after as position: absolute and place it based on the .box div, something like this :
.box {
width: 100px;
height: 20px;
border: 1px solid black;
position: relative; /* Made it relative */
}
.box:after {
content: '';
position: absolute;
display: block;
width: 20px;
height: 20px;
border: 1px solid blue;
top: -1px; /* To compensate the border on the main element */
background-color: blue;
left: 100%; /* To place it after the main element */
}
If you truly need another div, try adding some javascript, like this
$(document).ready(function() {
$('.box').append('<div class="another-box"></div>');
});
.box {
width: 100px;
height: 20px;
position: relative;
border: 1px solid black;
}
.box:after {
content: '';
width: 20px;
bottom: -1px;
right: -21px;
top: -1px;
position: absolute;
background-color: blue;
}
<div class="box"></div>

Creating a div with a pointed side

I want to create a div with an image and text in it that looks like this.
I've managed to get something that looks like this here:
JSFiddle of pointed div
.triangle-down {
background: white;
display: inline-block;
height: 125px;
margin-left: 20px;
margin-bottom: 55px;
position: relative;
width: 200px;
cursor: pointer;
border: red solid 2px;
}
img {
margin: 10px;
}
.triangle-down:before {
border-top: 20px solid red;
border-left: 101px solid transparent;
border-right: 101px solid transparent;
content: "";
height: 0;
left: -1px;
position: absolute;
top: 127px;
width: 0;
}
.triangle-down:after {
border-top: 20px solid white;
border-left: 100px solid transparent;
border-right: 100px solid transparent;
content: "";
height: 0;
left: 0;
position: absolute;
top: 125px;
width: 0;
}
<div class="triangle-down">
<img src="http://placehold.it/180x105">
</div>
The issues I have are:
(1) The curser turns to a pointer outside the shape when it crosses the transparent borders that help create the point. I'd prefer it if the pointer appeared only when inside the visible outline of the shape.
(2) Is there a better way of doing this? I looked at trying to rotate a div to create the point as I thought this would solve the pointer issue but I can't work out how to create an isosceles triangle shape with the correct proportions this way. This would also allow me to apply a border to create the outline rather than overlay two triangles as I have in the JSFiddle. See this post for more on this - Speech bubble with arrow
Here is a version using transform: rotate
/*Down pointing*/
.triangle-down {
background: white;
display: inline-block;
height: 125px;
margin-left: 20px;
margin-bottom: 55px;
position: relative;
width: 200px;
cursor: pointer;
border: red solid 2px;
}
img {
position: relative;
margin: 10px;
z-index: 1
}
.triangle-down:before,
.triangle-down:after {
border-bottom: 2px solid red;
background: white;
content: '';
height: 50px;
left: 5px;
position: absolute;
top: 98px;
width: 54%;
transform: rotate(22deg);
z-index: 0;
}
.triangle-down:after {
left: auto;
right: 5px;
transform: rotate(-22deg);
}
<div class="triangle-down">
<img src="http://placehold.it/180x105">
</div>

Box shape with right angled trapezoids

I'm wondering if this shape can be done in css3 with as little html as possible:
So far, I've managed to do this:
.wrapper {
position: relative;
}
.box {
width: 100px;
height: 100px;
border: 1px solid #000;
position: absolute;
top: 100px;
left: 100px;
}
.box:before {
content: "";
border: 1px solid #000;
border-bottom: 1px solid #fff;
width: 50%;
height: 10px;
position: absolute;
top: -12px;
left: -1px;
}
.box:after {
content: "";
border: 1px solid #000;
border-top: 1px solid #fff;
width: 50%;
height: 10px;
position: absolute;
bottom: -12px;
right: -1px;
}
<div class="wrapper">
<div class="box"></div>
</div>
The fiddle is here, but I don't know how to skew it like that so that I have right angled trapezoid on top and bottom.
The shape needs no extra elements
The shape can be created with just the <div>:
The left side is created with the divs left, top and bottom borders.
The right side is made by :before and its top, right and bottom borders
The spans joining the two boxes are created with the :after thanks to skewY
Note the browser support of the transform property. IE 9 requires the -ms- prefix, and Safari and the Android browser require -webkit-.
Working Example - just the shape
The CSS has been condensed and the border style of the pseudo elements is inherited from the div itself.
div {
border: solid 4px #000;
border-right-width: 0;
width: 100px;
height: 200px;
position: relative;
}
div:before,div:after {
content: '';
display: block;
height: 100%;
width: 100%;
border: inherit;
border-right-width: 4px;
border-left: none;
position: absolute;
left: 100%;
top: 13px;
margin-left: 20px;
}
div:after {
width: 20px;
border-right: none;
top: 5px;
transform: skewY(40deg);
margin: 0;
}
<div></div>
Working example - with text
With the example above, the contents will not be contained inside the entire shape. Rather, it will be constrained inside the divs half width. The contents needs to be wrapped in a <span> with 200% width to punch it outside of the divs constraints.
div {
border: solid 4px #000;
border-right-width: 0;
width: 100px;
height: 200px;
position: relative;
}
div:before,div:after {
content: '';
display: block;
height: 100%;
width: 100%;
border: inherit;
border-right-width: 4px;
border-left: none;
position: absolute;
left: 100%;
top: 13px;
margin-left: 20px;
}
div:after {
width: 20px;
border-right: none;
top: 5px;
transform: skewY(40deg);
margin: 0;
}
span {
width: 200%;
display: block;
padding: 20px 10px 10px;
}
<div><span>This is me writing a large amount of words into the div. I think that you may want a span in order to contain them.</span></div>
Using two different elements:
1) Separate the shape in two different rectangular
2)After use pseudo-elements after and before to create the connection line.
My approach:
.wrapper {
position: relative;
}
.box {
width: 50px;
height: 100px;
border: 4px solid #000;
position: absolute;
top: 100px;
left: 100px;
border-right: 0;
}
.box2 {
width: 50px;
height: 100px;
border: 4px solid #000;
position: absolute;
top: 112px;
left: 164px;
border-left: 0;
}
.box:after {
content: "";
position: absolute;
width: 15px;
border: 2px solid #000;
right: -15px;
top: 2px;
transform: rotate(45deg);
}
.box:before {
content: "";
position: absolute;
width: 15px;
border: 2px solid #000;
right: -15px;
bottom: -10px;
transform: rotate(45deg);
}
<div class="box"></div>
<div class="box2"></div>
I've used four divs: .left, .right, .middle-top and .middle-bottom; and skewed .middle-top and .middle-bottom to add those connection lines.
.left {
width: 40px;
height: 100px;
border: 3px solid black;
border-right: 1px solid white;
position: absolute;
top: 50px;
left: 100px;
}
.right {
width: 40px;
height: 100px;
border: 3px solid #000;
border-left: 1px solid white;
position: absolute;
top: 60px;
left: 160px;
}
.middle-top {
width: 20px;
height: 20px;
border-top: 3px solid black;
position: absolute;
transform: matrix(1, 0.5, -0.5, 1, 0, 0);
top: 55px;
left: 137px;
z-index: 9;
}
.middle-bottom {
width: 21px;
height: 20px;
border-top: 3px solid black;
position: absolute;
transform: matrix(1, 0.5, -0.5, 1, 0, 0);
top: 158px;
left: 135px;
z-index: 9;
}
<div class="left"></div>
<div class="middle-top"></div>
<div class="middle-bottom"></div>
<div class="right"></div>

Moving CSS content onto a border

Right, I ran into a bit of a problem and not to sure if this can be solved another way.
I need to move the content: "F"; and center it onto the border I have in the top left corner. Now is this possible without creating another element?
HTML:
<div class="userBoxF"></div>
CSS:
.userBoxF {
width: 200px;
height: 200px;
background: #eee;
border: 1px solid;
border-radius: 10px;
position: relative;
overflow: hidden;
}
.userBoxF:after {
content: "F";
position: absolute;
top: 0;
left: 0;
width: 0;
height: 0;
border: 40px solid #F385FF;
border-right-color: transparent;
border-bottom-color: transparent;
font-size: 30px;
}
The only way I can think to do it is to create the corner as a completely separate element so I can put the text "F" into a span (or something) and move it that way.
Demo Here
Note: Nothing here will change size, width and height for both the box and corner will always be the same.
Here is what I want, using the solution i found but would rather not use.
HTML:
<div class="userBoxF">
<div class="corner"><span>F</span></div>
</div>
CSS:
.userBoxF {
width: 200px;
height: 200px;
background: #eee;
border: 1px solid;
border-radius: 10px;
position: relative;
overflow: hidden;
}
.userBoxF .corner {
position: absolute;
top: 0;
left: 0;
width: 0;
height: 0;
border: 40px solid #F385FF;
border-right-color: transparent;
border-bottom-color: transparent;
font-size: 30px;
}
.userBoxF .corner span {
display: block;
position: absolute;
top: -30px;
left: -20px;
}
Here is a demo of the solution I came up with but I would rather not create anymore elements.
My Solution
You can use :before wit :after together.
I removed the span:
<div class="userBoxF">
</div>
And changed the CSS blocks to this:
.userBoxF:before {
position: absolute;
top: 0;
left: 0;
width: 0;
height: 0;
border: 40px solid #F385FF;
border-right-color: transparent;
border-bottom-color: transparent;
content: "";
}
.userBoxF:after {
display: block;
position: absolute;
top: 10px;
left: 14px;
content: "F";
font-size: 30px;
}
And here's the updated fiddle
EDIT: Here's an added bonus!
You can jack the "F" from the class, if you want it to be more versatile, if you use CSS's attr inside content. Example:
<div class="userBox" data-l="F">
</div>
And:
.userBox:after {
display: block;
position: absolute;
top: 10px;
left: 14px;
content: "" attr(data-l);
font-size: 30px;
}
And another fiddle
Arguably the "F" is actual content as it's not a styling option...it actually denotes something and, perhaps should be read by a screenreader (for instance) then a span with a gradient (TL - BR) mightbe more appropriate.
JSFiddle Demo
HTML
<div class="userBoxF">
<span class="section-letter">F</span>
</div>
CSS
.userBoxF {
width: 200px;
height: 200px;
background: #eee;
border: 1px solid;
border-radius: 10px;
position: relative;
overflow: hidden;
}
.section-letter {
position: absolute;
top: 0;
left: 0;
width:2em;
height:2em;
line-height: 1em;
text-align: left;
padding:0.25em 0 0 0.25em;
font-size: 30px;
background: linear-gradient(135deg, pink 0%, pink 50%, transparent 50%, transparent 100%);
}
Simply use another :psuedo:
Demo Fiddle
.userBoxF {
width: 200px;
height: 200px;
background: #eee;
border: 1px solid;
border-radius: 10px;
position: relative;
overflow: hidden;
}
.userBoxF:before,.userBoxF:after{
position: absolute;
top: 0;
left: 0;
}
.userBoxF:before {
content:"";
border: 40px solid #F385FF;
border-right-color: transparent;
border-bottom-color: transparent;
}
.userBoxF:after {
content:attr(data-l);
top: 10px;
left: 10px;
font-size: 30px;
}
From a single pseudo, you can use a gradient as background : DEMO
.userBoxF {
width: 200px;
height: 200px;
background: #eee;
border: 1px solid;
border-radius: 10px;
position: relative;
overflow: hidden;
}
.userBoxF:after {
content:"F";
position: absolute;
top: 0;
left: 0;
text-indent:20px;
line-height:60px;
width:80px;
height:80px;
background:linear-gradient(to bottom right, #F385FF 51%, transparent 49%);
font-size: 30px;
}
background-image as gradient can be just an image like in old days :
