I want to create an odd shaped triangle with css. My first thought was to use transparent borders with transform: rotate and it worked (see left triangle). Now I want to use a gradient border image pattern as background for a same triangle but I can't make it work. I tried many things like changing border-width, using wrappers and overflow:hidden among others, nothing worked. Here I post one of my tries (see right shape) as you see the pattern takes all the space, not following the triangle shape. Any ideas?
#top-left {
position:absolute;
left:78px;
width: 0;
height: 0;
border-top: 100px solid transparent;
border-right: 80px solid black;
border-bottom: 50px solid transparent;
-webkit-transform: rotate(-20deg);
}
#top-right {
position:absolute;
left:300px;
width: 0;
height: 0;
border-image: repeating-linear-gradient( 0deg, pink, pink 1%, purple 1%, purple 8%) 10;
border-image-width: 100px 80px 50px 0px;
border-width: 100px 80px 50px 0px;
border-style: solid;
-webkit-transform: rotate(-20deg);
}<div id="wrapper">
<div id="top-left"></div>
<div id="top-right"></div>
</div>Edit: Andrey Fedorov's answer is good, but there is a problem when the background is not a solid color, like this for example:
body{
background-color: #6d695c;
background-image:
repeating-linear-gradient(120deg, rgba(255,255,255,.1), rgba(255,255,255,.1) 1px, transparent 1px, transparent 60px),
repeating-linear-gradient(60deg, rgba(255,255,255,.1), rgba(255,255,255,.1) 1px, transparent 1px, transparent 60px),
linear-gradient(60deg, rgba(0,0,0,.1) 25%, transparent 25%, transparent 75%, rgba(0,0,0,.1) 75%, rgba(0,0,0,.1)),
linear-gradient(120deg, rgba(0,0,0,.1) 25%, transparent 25%, transparent 75%, rgba(0,0,0,.1) 75%, rgba(0,0,0,.1));
background-size: 70px 120px;
}
#wrapper {
position: relative;
}
#top-left {
position:absolute;
left:0px;
width: 0;
height: 0;
border-top: 100px solid #fff;
border-right: 80px solid transparent;
border-bottom: 50px solid #fff;
-webkit-transform: rotate(-20deg);
}
#top-right {
position:absolute;
z-index: -10;
left:0;
width: 0;
height: 0;
border-image: repeating-linear-gradient( 0deg, pink, pink 1%, purple 1%, purple 8%) 10;
border-image-width: 100px 80px 50px 0px;
border-width: 100px 80px 50px 0px;
border-style: solid;
-webkit-transform: rotate(-20deg);
}<div id="wrapper">
<div id="top-left"></div>
<div id="top-right"></div>
</div>You still can use linear-gradient with no-repeat and background-size to draw each pieces :
examples by steps from a single tag :
/* testing gradients */
p , div#wrapper {
width:80px;
float:left;
margin:1em;
height:150px;
/* see me then remove this shadow */
box-shadow:0 0 0 2px;
}
p {
background:
linear-gradient(130deg, transparent 49.75%, pink 50.5%) 0 42px no-repeat ;
background-size:
100% 15px;
transform: rotate(-20deg);
}
p + p{
background:
linear-gradient(130deg, transparent 49.75%, pink 50.5%) 0 42px no-repeat ,
linear-gradient(130deg,transparent 62px, purple 63px) top no-repeat;
background-size:
100% 15px,
100% 65%;
}
p + p + p {
background:
linear-gradient(130deg, transparent 49.75%, pink 50.5%) 0 42px no-repeat ,
linear-gradient(130deg,transparent 62px, purple 63px) top no-repeat,
linear-gradient(33deg , transparent 42px, pink 43px) no-repeat bottom;
background-size:
100% 15px,
100% 65%,
100% 8px;
}
p+ p + p + p {
background:
linear-gradient(130deg, transparent 49.75%, pink 50.5%) 0 42px no-repeat ,
linear-gradient(130deg,transparent 62px, purple 63px) top no-repeat,
linear-gradient(33deg , transparent 42px, pink 43px) no-repeat bottom,
linear-gradient(33deg, transparent 42px, purple 43px) bottom no-repeat;
background-size:
100% 15px,
100% 65%,
100% 8px,
100% 35.5%;
}
p:last-of-type{
box-shadow:0 0
}

<p></p>inbricated element + gradient & transform could do too:
body{

background-image:
repeating-linear-gradient(120deg, rgba(255,255,255,.1), rgba(255,255,255,.1) 1px, transparent 1px, transparent 60px),

linear-gradient(60deg, rgba(0,0,0,.1) 25%, transparent 25%, transparent 75%, rgba(0,0,0,.1) 75%, rgba(0,0,0,.1)),
linear-gradient(120deg, rgba(0,0,0,.1) 25%, transparent 25%, transparent 75%, rgba(0,0,0,.1) 75%, rgba(0,0,0,.1));
background-size: 70px 120px;
}
div.inbricate {
margin:1em;
height:150px;
width:80px;
position:relative;
overflow:hidden;
transform:rotate(-20deg);
box-shadow: 0 0 ;
}
.inbricate div {
transform:rotate(31deg) scale(1.2, 0.9) skew(-5deg);
transform-origin: 100% 102%;
height:100%;
background:linear-gradient(-40deg, pink 8%, purple 8%, purple 65%, pink 65%, pink 75%, purple 75% )
}<div class=inbricate>
<div>
</div>
