How CSS Triangles Work
CSS triangles are created using the border trick. When an element has zero width and height, its borders form triangles at each edge. By making the opposite border solid and the adjacent borders transparent, you get a triangle pointing in the desired direction. This technique is widely supported and requires no images or SVG.
