I want to use basic CSS to make triangle in an HTML page. I am using triangle pics which take time to load, so, I want to decrease loading time of my page.
Not possible with HTML, but with CSS. Example:
<div class="triangle></div>
.triangle {
width: 0;
height: 0;
border: solid 30px;
border-color: transparent transparent black transparent;
}
Live demo: jsFiddle
30px
in the border
property defines the size: width and height. You can change it if you want a smaller or a bigger triangle.black
and transparent
in the border-color
property. See jsFiddle
This is the best explanation on how to create CSS triangles: http://www.uselesspickles.com/triangles/
By creating divs without width or height, the borders end up creating a triangle when you leave some of the borders as transparent.
Credit That page was written by a co-worker, way before other people figured out this trick.
#tri {
width: 0;
height: 0;
border-top-width: 20px;
border-top-style: solid;
border-top-color: transparent;
border-right-width: 20px;
border-right-style: solid;
border-right-color: red;
}
<div id="tri"></div>
