CSS Triangle Generator

Q: What is the alternative using clip-path?

You can create triangles with clip-path: polygon(), which clips an element to a given shape. For example, an upward triangle: clip-path: polygon(50% 0%, 0% 100%, 100% 100%). This approach lets you set background colors normally and supports gradients, whereas the border trick limits you to a solid color. The clip-path approach also works with background images. Use clip-path for modern projects and the border trick for maximum legacy compatibility.

Frequently Asked Questions

CSS triangles use the border rendering behavior of elements with zero width and height. When you set an element's width and height to 0 and give it thick borders, the corners of those borders are rendered diagonally — creating triangular shapes. By making three borders transparent and one colored, you get a triangle pointing in the direction of the colored border. It is a pure CSS trick requiring no images, SVGs, or JavaScript.

The border trick has universal browser support including very old browsers. For modern projects, clip-path: polygon() is often a better alternative — it is more intuitive, supports any polygon shape, and plays well with transforms and animations. However, clip-path has slightly less support in very old IE. The border trick is fine for tooltips, dropdown arrows, and decorative elements. For complex shapes, consider inline SVG or clip-path.
