Progressive Blur Skill

Workflow

  1. Confirm placement (top or bottom), height, and z-index relative to UI.
  2. Provide the matching snippet and a short usage checklist.
  3. Offer only targeted tweaks (height, blur steps, direction, opacity stops).

Usage checklist

  • Insert the HTML inside <body>.
  • Keep the .gradient-blur element near the top of the DOM.
  • Ensure the background behind it exists (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>

    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;

</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 to control smoothness.

Common pitfalls

  • backdrop-filter needs content behind it; it will not blur a flat background.
  • High blur values are GPU-heavy; reduce steps on low-end devices.
  • Ensure pointer-events: none stays to avoid blocking clicks.

Questions to ask when specs are missing

  • Should the blur start from the top or bottom?
  • How tall should the blur area be?
  • Is performance a concern on lower-end devices?
