Did you know you can create triangles using just CSS?
Whether you're building dropdown arrows, tooltip tails, or directional icons — you often need triangle shapes in web design. But instead of using image files, you can create lightweight, scalable CSS-only triangles.
The CSS Triangle Generator helps you do exactly that — no coding required.
What can it do?
  • Direction control: Choose from top, bottom, left, right, etc.
  • Color selector: Pick your triangle's color using HEX codes
  • Width & height sliders: Set the size visually
  • Auto-generated CSS code: Copy & paste the result instantly
  • Live preview: See how your triangle looks in real-time
The triangle is built using CSS borders. By setting width: 0 and height: 0 on a div and adjusting its borders, you can create clean triangle shapes of any direction.
How to use
  1. Select the direction of the triangle
  2. Choose the fill color
  3. Adjust width and height sliders to match your layout
  4. Copy the generated CSS and paste it into your stylesheet
width: 0;
height: 0;
border-style: solid;
border-width: 0 50px 100px 50px;
border-color: transparent transparent #000000 transparent;
Use cases
  • Tooltip arrows or chat bubble tails
  • Dropdown or accordion icons
  • Custom indicators or pointers in UI
  • CSS-only animations (e.g., spinning triangles)
  • Speed-optimized UI without images
