The CSS coin border generator builds a decorative milled coin edge, the ridged perforated ring you see around the rim of a physical coin, using only CSS. It draws the dashes with a repeating conic gradient masked to a thin ring around a circle, so there are no images and no dependencies. Tune the coin size, face and dash colors, ring thickness, and the number of dashes, then preview the result live and copy the HTML and CSS. Because it relies on CSS masks, it works in current evergreen browsers. Everything is generated locally in your browser with nothing uploaded.
Short answers for the questions people usually have before trying a utility like this.
A repeating conic gradient draws evenly spaced radial dashes, and a radial-gradient mask hides everything except a thin outer ring, leaving the milled coin edge around the circle.
It uses CSS mask, which works in current versions of Chrome, Edge, Firefox, and Safari. The snippet includes the -webkit-mask prefix for wider Safari coverage.
Yes. The markup and CSS are produced entirely in your browser, so nothing is uploaded and you can use the output freely.
