How to place something in a triangle-shaped box?

Tags: html,css,html5

Problem :

I found various examples of how to create triangles using CSS (like this one); all of them are based on creating a 0-sized box and fiddling with borders to create the triangle shape. Ok, very nice.

But how can I actually place something inside such a triangle?

Solution :

You can use positioning techniques to place some content over the triangle and not under the triangle..

I emphasized over and under because using positioning am positioning the text over the triangle, so triangle element isn't the parent of the content, as to create triangles we use height: 0; and width: 0; so you need to overlay the text.

Just make sure you use position: relative; for parent element holding absolute positioned element.

Didn't used z-index but you can use that to play safe with the stacking order.


<div class="wrap">
    <div class="triangle"></div>

div.wrap {
    position: relative;

div.triangle {
    height: 0;
    width: 0;
    border: 50px solid #f00;
    border-top-color: transparent;
    border-left-color: transparent;
    border-right-color: transparent;

div span {
    position: absolute;
    left: 35px;
    bottom: 0;
