What is progressive-blur?

A layered CSS overlay that gradually increases or decreases background blur from the top or bottom edge of the viewport. It uses several blur layers and masks to create a smooth fade.

It helps add top or bottom blur overlays behind fixed navigation, interface elements, or other content that needs depth and softness.

A single blur layer often creates a hard or uneven edge. Progressive layers make content near the edge softer while keeping the rest of the page readable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.02309
Opus 5	$0.00026	$0.01154

Security

Grade A, and why

progressive-blur scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to progressive-blur — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Progressive Blur Skill

Workflow

Confirm placement (top or bottom), height, and z-index relative to UI.
Provide the matching snippet and a short usage checklist.
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.
