CSS Triangle Generator

The CSS Triangle Generator helps you create triangle shapes using pure CSS. This technique relies on the way browsers render borders when they meet at corners.

How it works

By setting an element's width and height to 0 and applying thick borders, you can create triangles. The transparent borders create the angled sides, while the colored border creates the visible triangle.

Common Uses

• Tooltips: Create the little arrow pointing from a tooltip to its target.
• Dropdowns: Indicate that a menu can be expanded.
• Breadcrumbs: Separate navigation items.
• Decorative Elements: Add geometric flair to your design.
