Progressive Blur Skill
When to use
- Smooth blur transitions at top/bottom of sections
- Hero overlays, navigation backgrounds, content fade-outs
- Modern glassmorphism effects
Usage checklist
- Insert the HTML inside
<body>
- Keep
.gradient-blur near the top of the DOM
- Ensure background content exists behind it (backdrop-filter blurs what is behind)
- Adjust
z-index to sit above content but below modals
Top blur (from top)
<div class="gradient-blur">
<div></div><div></div><div></div><div></div><div></div><div></div>
</div>
<style>
.gradient-blur {
position: fixed; z-index: 5;
inset: 0 0 auto 0; height: 12%;
pointer-events: none;
}
.gradient-blur > div, .gradient-blur::before, .gradient-blur::after {
position: absolute; inset: 0;
}
.gradient-blur::before {
content: ""; z-index: 1; backdrop-filter: blur(0.5px);
mask: linear-gradient(to top, rgba(0,0,0,0) 0%, rgba(0,0,0,1) 12.5%, rgba(0,0,0,1) 25%, rgba(0,0,0,0) 37.5%);
}
{
: ; : ; : ();
: (to top, (,,,) , (,,,) );
}
</style>
Customization knobs
- Direction: Flip
to top ↔ to bottom
- Height: Adjust
.gradient-blur height percentage
- Strength: Change blur values (0.5px → 64px)
- Steps: Add/remove layers for smoothness control
Common pitfalls
backdrop-filter needs content behind it — won't blur a flat background- High blur values are GPU-heavy — reduce steps on low-end devices
pointer-events: none is essential to avoid blocking clicks
Tips for AI Agents
- Ask whether blur should start from top or bottom.
- Confirm height of blur area.
- Consider performance constraints on mobile devices.
