+# custom fonts
+
+to change the fonts in the web-UI,  first create a css file with your customizations, for example `customfonts.css`, for example in your webroot
+
+add this to your copyparty config so the css file gets loaded: `--html-head='<link rel="stylesheet" href="/customfonts.css">'`
+
+make your changes in the css file; this is the default values to get you started:
+
+```css
+:root {
+	--font-main: sans-serif;
+	--font-serif: serif;
+	--font-mono: 'scp';
+}
+```
+
+if you are introducing a new ttf/woff font, don't forget to declare the font itself in the css file; here's one of the default fonts from `ui.css`:
+
+```css
+@font-face {
+	font-family: 'scp';
+	font-display: swap;
+	src: local('Source Code Pro Regular'), local('SourceCodePro-Regular'), url(deps/scp.woff2) format('woff2');
+}
+```
