CSS Triangle Generator Reference & Specifications

The CSS Triangle Generator creates arrow and pointer shapes with pure CSS borders - the classic technique for tooltips, dropdown arrows, and callout pointers. The border trick is compact but fiddly to remember, so the generator produces it instantly.

You pick orientation, size, and color, and paste the single CSS class into your project to get an arrow that scales and colors with your design.

Frequently Asked Questions

Why use borders instead of a character or SVG?

A border triangle is a single element with no extra markup or asset, so it is ideal for tiny UI pointers where simplicity matters.

Can I outline the triangle?

True outlines need more markup. For most pointers a solid accent color matches the panel they point to.
