Create div with triangle border in css - css

I am trying to create a div with arrow on left and right. No background, only border. Something like this:
I am able to create similar div with filled background color using ::before and ::after tags. However, only borders is something i am not able to achieve. Can it be done with css only?
https://jsfiddle.net/1g16x8p7/1/
html:
<div class="wizard">
<a class="item">
</a>
</div>
css:
.item {
display: inline-block;
padding: 15px;
padding-left: 25px;
/*default styles*/
background-color: green;
position: relative;
}
.item:before,
.item:after {
content: "";
height: 0;
width: 0;
border-width: 15px 0 15px 10px;
border-style: solid;
position: absolute;
left: 100%;
top: 0;
}
.item:before {
border-color: transparent transparent transparent white;
left: 0;
}
.item:after {
border-color: transparent transparent transparent green;
}

You can use ::before and ::after with borders on two adjacent sides (e.g. top and right) and then transform: rotate and position: absolute them to create the left and right parts, e.g.
<div class="arrow"></div>
.arrow {
height: 75px;
width: 200px;
border-top: 4px solid black;
border-bottom: 4px solid black;
position: relative;
}
.arrow::before, .arrow::after {
content: "";
border-top: 4px solid black;
border-right: 4px solid black;
height: 55px;
width: 55px;
position: absolute;
transform: rotate(45deg);
}
.arrow::before {
top: 8px;
left: -30px;
}
.arrow::after {
top: 8px;
right: -30px;
}
Here's an example.

How to give border to a shape?

I am building a testimonial component in react and I have to make a shape direction towards pic, I have done the shape exactly how I want but the testimonial div has border color when I apply the div gets a border but the shape is left outside I have tried several ways but couldn't find a solution, I have attached the picture of what I want and how it is right now.
How I want it
What I have achieved till now
Below is my CSS
#page {
background-color: lightgray;
padding: 40px;
}
.container {
position: relative;
background-color: #FFFFFF;
max-width: 600px;
height: auto;
border: 1px solid #E7E7E7;
padding: 30px;
box-sizing: border-box;
}
.container:after {
position: absolute;
width: 0;
height: 0;
border-top: 50px solid white;
border-right: 40px solid transparent;
top:101%;
left: 40%;
content: '';
transform: rotate(14deg);
margin-top: -10px;
}
<div id="page">
<div class="container">This is a test</div>
</div>
You may use a filter , choice: drop-shadow.
support ? , don't be afraid : https://caniuse.com/?search=drop-shadow All but IE 6-11 and Opera mini
here is an exemple to run:
#page {
background-color: lightgray;
padding: 40px;
}
.container {
position: relative;
background-color: #FFFFFF;
max-width: 600px;
height: auto;
filter:
/* draw borders without blur*/
drop-shadow(0 1px )
drop-shadow(1px 0px )
drop-shadow(0 -1px )
drop-shadow(-1px 0px )
/* add eventually a shadow */
drop-shadow(0 0 3px )
/*and another for demo purpose */
drop-shadow(30px 30px 3px gray );
padding: 30px;
box-sizing: border-box;
}
.container:after {
position: absolute;
width: 0;
height: 0;
border-top: 50px solid white;
border-right: 40px solid transparent;
top:101%;
left: 40%;
content: '';
transform: rotate(14deg);
margin-top: -10px;
}
<div id="page">
<div class="container">This is a test</div>
</div>
You can use a :before that's 1px bigger than your :after which uses the border colour instead and then it will be mostly covered by the :after, giving you your "fake" border. Just makes sure your z-indexing is correct so it doesn't show inside your bubble.
EDIT: Adding in example css.
I modified some colours and spacing for illustrative purposes:
#page {
background: #ffc;
padding: 40px 40px 60px;
position: relative;
z-index: 0;
}
.container {
position: relative;
background: #fff;
max-width: 600px;
height: auto;
border: 1px solid #000;
padding: 30px;
box-sizing: border-box;
}
.container:after,
.container:before {
position: absolute;
width: 0;
height: 0;
top: 101%;
left: 40%;
content: "";
transform: rotate(14deg);
margin-top: -10px;
}
.container:after {
border-top: 50px solid #fff;
border-right: 40px solid transparent;
}
.container:before {
border-top: 52px solid #000;
border-right: 42px solid transparent;
margin-left: -1px;
z-index: -1;
}
<div id="page">
<div class="container">This is a test</div>
</div>
Adding both a :before and :after is a good idea to get the effect you want. Using a CSS box-shadow or outline won't work because it actually renders a complete square around your arrow/triangle shape. A z-index is added to the before to push it to the background. In that way it's not overlapping the other objects.
Here's an example of what you might want. You can adjust the border sizes to finetune it.
.container {
position: relative;
background-color: #FFFFFF;
max-width: 600px;
height: auto;
border: 1px solid #E7E7E7;
padding: 30px;
box-sizing: border-box;
}
.container:before {
position: absolute;
width: 0;
height: 0;
border-top: 53px solid #e7e7e7;
border-right: 43px solid transparent;
top: 100%;
left: 40%;
content: '';
transform: rotate(14deg);
margin-top: -10px;
z-index: -1;
}
.container:after {
position: absolute;
width: 0;
height: 0;
border-top: 50px solid white;
border-right: 40px solid transparent;
top:101%;
left: 40%;
content: '';
transform: rotate(14deg);
margin-top: -10px;
}
<div class="container"></div>

Create this shape in CSS (half pipe shape)

I've been trying to make this shape in CSS, but unfortunately could not find a way how to. It's half pipe like shaped:
The pixelated corner should be smooth (it's a zoomed in image).
Anyone knows how to create this? Or can get me on the right tracks?
You will need to use pseudo element :after for the inner block and then apply border-radius for curved corner.
div {
height: 60px;
width: 60px;
border: solid red;
position: relative;
background: red;
border-width: 0 10px 10px 0;
box-sizing: border-box;
}
div:after {
content: "";
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
border-bottom-right-radius: 10px;
background: #fff;
}
<div></div>
simple
.shape {
width: 140px;
height: 200px;
background-color: gray;
}
.shape:after {
content: '';
position: absolute;
width: 100px;
height: 160px;
background-color: #fff;
border-bottom-right-radius: 50px;
}
<div class="shape"></div>
I assume that the problem here is to create the "outer" curve, on the arbitrary background. It's achievable by the trick with clipping the needed part from the thick rounded border of the pseudo-element:
div {
width: 50%;
min-height: 4em;
margin: auto;
border: #888 solid;
border-width: 0 1em 1em 0;
position: relative;
}
div::after {
content: '';
border: #888 solid;
border-width: 0 1em 1em 0;
border-radius: 0 0 100% 0;
position: absolute;
right: -1em;
bottom: -1em;
width: 1em;
height: 1em;
clip: rect(0 1em 1em 0);
}
div:hover::after {
border-color: red; /* highlight the curved part */
}
body {
/* just as a background example */
background: repeating-linear-gradient(-45deg, #ddd, #ddd 1px, transparent 1px, transparent 10px);
min-height: 90vh;
}
<div></div>
You can do this with one element and with transparency like this:
.box {
width:80px;
height:100px;
border-right:20px solid grey;
border-bottom:20px solid grey;
box-sizing:border-box;
background:
radial-gradient(farthest-side at top left,transparent 98%,grey ) bottom right/20px 20px no-repeat;
}
body {
background:pink;
}
<div class="box">
</div>

Create an arrow with a mouseover effect

I'd like to create a simple arrow with a mouseover effect. I create a span and a triangle. But now I need a mouseover effect which should apply to the whole arrow. Any Idea? I put my Sourcetext in a fiddle.

position: relative;
}
.series-triangle:after {
content: '';
position: absolute;
top: 3px;
left: -3px;
width: 0;
height: 0;
border-color: transparent transparent transparent #EFDF00;
border-style: solid;
border-width: 31px;
}
.series-triangle:before {
content: '';
position: absolute;
top: 1px;
left: -2px;
width: 10;
height: 10;
border-color: transparent transparent transparent #444;
border-style: solid;
border-width: 33px;
}
.series-triangle:hover {
background-color: white;
}
.rectangle {
float:left;
height: 60px;
border: 2px solid #444;
padding: 2px;
text-align: center;
border-radius: 5px;
background-color: #EFDF00;
}
.rectangle:hover {
background-color: white;
}

Put them in a parent element and react to the :hover state of the parent :
HTML :
<div class="parent">
<span id="series" class="rectangle"></span>
<div class="series-triangle">
</div>
</div>
CSS :
.parent:hover .rectangle, .parent:hover .series-triangle{
/* Do something */
}
Example with color change for both parts on parent hover :

Make Ribbon Appear Behind Rectangle

I am trying to create a ribbon at the beginning of a rectangle. However, I cannot figure out how to make it appear BEHIND the rectangle.
Please see this codepen: http://codepen.io/gosusheep/pen/aOqOBy
The part for creating the ribbon and putting it behind the rectangle is here:
.rectangle::before{
content: "";
width: 0;
height: 0;
display: block;
position: absolute;
z-index: -1;
border-left: 25px solid transparent;
border-right: 25px solid $blue;
border-top: 25px solid $blue;
border-bottom: 25px solid $blue;
left: -30px;
top: 10%;
}
Even with position: absolute, and z-index: -1, it appears ON TOP of the div.
Can anyone help with this?
What is happening here is that apparently, the property transform: translateX(-50%); it's "overriding" in some way the z-index. My solution is just center rectangle otherwise, for example:
.rectangle{
margin: 0 auto;
}
DEMO
The reason for your problem is not because children cannot be positioned behind their parent but because you are using a transform on the parent. Using transforms affect the stacking context like mentioned in this answer by BoltClock.
One solution would be to avoid the transform totally and use left: calc(50% - 100px) instead to position the ribbon at the center (like in the below snippet). (50% - 100px) is used as the value because 100px is half of the box width (50% is the center point of the parent).
.rectangle {
width: 200px;
height: 50px;
background-color: #8080ff;
position: relative;
left: calc(50% - 100px); /* newly added */
border: 1px #6666ff solid;
}
ul {
list-style: none;
}
li {
display: inline;
}
li + li::before {
content: " | ";
}
.container {
width: 100%;
position: relative;
}
.rectangle {
width: 200px;
height: 50px;
background-color: #8080ff;
position: relative;
left: calc(50% - 100px); /* newly added */
border: 1px #6666ff solid;
}
.rectangle::before {
content: "";
width: 0;
height: 0;
display: block;
position: absolute;
z-index: -1;
border-left: 25px solid transparent;
border-right: 25px solid #8080ff;
border-top: 25px solid #8080ff;
border-bottom: 25px solid #8080ff;
left: -30px;
top: 10%;
}

If in case you can't use the above solution, then you could follow the approach described below.
Assuming you don't have any other use for the ::after pseudo-element, you could use that to create the rectangle and give it a z-index higher than the ::before pseudo-element to make it appear behind the rectangle.
/* Modified */
.rectangle {
width: 200px;
height: 50px;
position: relative;
left: 50%;
transform: translateX(-50%);
}
/* Added */
.rectangle::after {
content: "";
width: 100%;
height: 100%;
top: 0px;
left: 0px;
display: block;
position: absolute;
background-color: #8080ff;
border: 1px #6666ff solid;
z-index: -1;
}
.rectangle{
padding: 4px;
box-sizing: border-box;
}
Below is a sample snippet:
ul {
list-style: none;
}
li {
display: inline;
}
li + li::before {
content: " | ";
}
.container {
width: 100%;
position: relative;
}
.rectangle::before {
content: "";
width: 0;
height: 0;
display: block;
position: absolute;
z-index: -2;

border-top: 25px solid #8080ff;
border-bottom: 25px solid #8080ff;

</div>
Solution here, look closely at z-indexes and positions
.container{
position: relative;
width: 100%;
z-index: 1;
}
.rectangle{
width: 200px;
height: 50px;
background-color: $blue;
position: absolute;
left: 50%;
border: 1px darken($blue,5%) solid;
}
.rectangle::after{
content: "";
width: 0;
height: 0;
border-left: 25px solid transparent;
border-right: 25px solid $blue;
border-top: 25px solid $blue;
border-bottom: 25px solid $blue;
left: -30px;
top: 10px;
position: absolute;
z-index: -1;
}

HTML line with a downward arrow

I am trying to draw a line with a small arrow pointing down as in the image attached.
I have not been able to get the downward arrow. Is there a way I can do it using html and css?
HTML
<hr class="line">
CSS
.line{
width:70%;
color:red;
}
http://jsfiddle.net/4eL39sm1/
Thanks.
You can use pseudo-elements :after and :before:
.line {
width:70%;
}
.line:after {
content:'';
position: absolute;
border-style: solid;
border-width: 7px 7px 0;
border-color: #FFFFFF transparent;
display: block;
width: 0;
z-index: 1;
top: 8px;
left: 45%;
}
.line:before {
content:'';
position: absolute;
border-style: solid;
border-width: 7px 7px 0;
border-color: #7F7F7F transparent;
display: block;
width: 0;
z-index: 1;
top: 9px;
left: 45%;
}
<hr class="line">
You can play with border-width to adjust the size to your needs.
