</button>How this button is built
- Background: a solid #0b0b14 fill.
- Type: Inter, weight 600, 15px, in #ede9fe.
- Shape: 12px rounded corners with 14px × 28px padding, plus a 1px solid border.
- Depth: a coloured glow.
- Interaction: on hover it lifts 1px, 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 Inter 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.
