</button>How this button is built
- Background: a 2-stop
linear-gradient()at 180° (#f8fafc → #e2e8f0). - Type: JetBrains Mono, weight 700, 14px, uppercase, letter-spacing 4px, in #334155.
- Shape: 8px rounded corners with 12px × 22px padding, plus a 1px solid border.
- Depth: a hard offset shadow with no blur, which gives it physical depth and an inset highlight along the edge.
- Interaction: on hover it lifts 1px, brightens slightly and nudges its icon, and it presses down 5px when clicked, with 120ms 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.
