How this button is built
- Background: a 2-stop
linear-gradient()at 180° (#86efac → #4ade80). - Type: Fredoka, weight 600, 18px, in #052e16.
- Shape: a fully rounded pill shape with 14px × 28px padding.
- Depth: a coloured glow and an inset highlight along the edge.
- Interaction: on hover it lifts 2px, scales to 108% and brightens slightly, and it squishes slightly when clicked, with 300ms 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 Fredoka 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.
