What is CSS Triangle Generator?
Pure CSS triangles and arrows are created by manipulating borders on elements with zero width and height — a classic CSS trick for tooltips, dropdown arrows, breadcrumb shapes, and decorative elements without SVG or image files. DailyDevTools' CSS Triangle Generator lets you configure direction, size, and color visually and copies the complete CSS instantly.

- 2Adjust the size using the width and height sliders
- 3Pick the triangle color using the color picker
- 4Copy the CSS (which uses border manipulation to create the triangle) into your stylesheet
Frequently asked questions
How do CSS triangles work?
Triangles use an element with zero width and height but thick borders. A transparent top, left, and right border with a colored bottom border creates a downward-pointing triangle. The border corners create diagonal lines that form the triangle shape.
Should I use CSS triangles or SVG for arrows?
CSS triangles work well for simple decorative arrows in UI components. SVG is better when you need scaling at multiple sizes, accessibility (title/desc elements), or animation. For tooltips and small UI indicators, CSS triangles are perfectly fine.
Can I make a right-angle triangle with CSS?
Yes. Use different border widths for adjacent sides: a large bottom border and smaller left border creates a right-angle triangle pointing up-right. The generator handles all standard triangle orientations including diagonal variants.
