CSS Triangle Arrow Generator
Generate border-based CSS triangles and arrows.
Triangles and arrows in CSS
The classic border trick turns an empty element into a triangle — the basis for tooltips, dropdown carets, and speech-bubble tails. Remembering which borders to set transparent is annoying. This generator builds the triangle CSS in any direction with a preview.
It saves you from re-deriving the border-color puzzle every time. Pick the direction and size, preview the shape, and copy the CSS to add a crisp arrow or caret without an image or icon font.
Copy-ready CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
