</button>How this button is built
- Background: a translucent fill (#000000 at 85% opacity).
- Type: JetBrains Mono, weight 700, 14px, uppercase, letter-spacing 10px, in #4ade80.
- Shape: 4px rounded corners with 14px × 28px padding, plus a 1px solid border.
- Depth: a coloured glow, an inset highlight along the edge and a text shadow.
- Interaction: on hover it brightens slightly, glows and nudges its icon, and it squishes slightly when clicked, with 200ms transitions.
- Accessibility: a visible
:focus-visiblering for keyboard users, and all motion turns off underprefers-reduced-motion.
How to use it
- Copy the CSS into your stylesheet. The
@importline loads the JetBrains Mono font from Google Fonts. Move it to the top of your file, or drop it if you already load the font. - Paste the HTML where you want the button. It works on
<button>,<a>and<input type="submit">. - Change the label, or rename the
.btnclass if it clashes with your framework. Want a different colour or size? Open it in the editor, change it visually, and copy the new code.
