How to draw a triangle with CSS?

Good day!

Please tell me whether it is possible to draw a triangle HOLLOW(!) a bunch of html+css

.av_triangl {
border: 5px solid transparent;
border-top: 8px solid #fff;
display: block;
width: 0;
height: 0;
margin: 5px auto;
}
This code draws a filled color. And I need empty!)

Can anybody have a solution..? Help!
