linear-gradient()at 135° (#f0abfc → #a5b4fc). - Type: Sora, weight 700, 16px, in #2e1065.
- Shape: 14px rounded corners with 14px × 28px padding, plus a 1px solid border.
- Depth: a coloured glow.
- Interaction: on hover it brightens slightly and glows, 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 Sora 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.
