Frequently Asked Questions

How do CSS triangles work?

CSS triangles use the border property. When an element has zero width/height, its borders meet at angles. By making some borders transparent and one colored, a triangle shape appears.

Can I create triangles pointing diagonally?

Yes! By adjusting border widths, you can create triangles pointing to corners. This tool supports the four main directions, but you can modify the CSS for diagonal variants.

Are CSS triangles accessible?

CSS triangles are decorative and typically should be hidden from screen readers using aria-hidden="true" on the element.
