Pure CSS Magic

No images, no SVG—just clever border tricks! Our CSS Triangle Generator creates arrows, pointers, and geometric shapes using the classic "transparent border" technique. Perfect for tooltip arrows, dropdown indicators, breadcrumb separators, and decorative accents. Pick direction, size, and color—copy the CSS—done!

The Zero-Size Trick

This generator exploits how browsers render borders on zero-width/height elements. Set one border colored, the rest transparent—a triangle appears! It's a hack so reliable it became standard practice. For more complex shapes, consider clip-path, but for simple arrows, this method is bulletproof!

CSS Archaeology: The border-triangle trick dates back to early CSS2 days (late 1990s). Despite dozens of new CSS features, it remains the go-to method for simple arrow shapes!
