Z-Index Exorcist

Powered by Cloudflare Workers AI — maps stacking contexts, detects conflicts, and suggests elegant fixes without !important.

CSS / component code

.modal { position: fixed; z-index: 9999; } .navbar { position: sticky; top: 0; z-index: 100; } .tooltip { z-index: 99999; }/* Modal appears behind navbar on Safari */

React Portal recommended

The sticky navbar creates its own stacking context, so no z-index on .modal can win from inside the page tree. Render the modal at document.body instead.

import { createPortal } from "react-dom";

// Renders outside all stacking contexts
createPortal(<YourModal />, document.body)

.modal

z-index: 9999stacking context: .navbar (position: sticky)

9999 loses to the navbar's context on Safari — the number is meaningless once a parent creates its own stacking context.

Portal the modal to document.body and drop it to z-index: 50.

Elegant solution

Adopt a three-tier scale — content (0–10), sticky chrome (100), overlays via portal (1000) — and delete every other z-index. Three tiers, zero !important, no arms race.

Den riktiga Z-Index Exorcist-modulen — samma tema, samma layout som appen. Exempeldata.

Problemet

The dropdown is behind the modal, the modal is behind the tooltip, and the "fix" is another z-index: 99999. Stacking contexts are invisible — which is exactly why they haunt every codebase.

Så gör sSystm det

The Z-Index Exorcist maps the actual stacking contexts in your CSS — which element creates which context, why the dropdown loses — and shows the real fix instead of the next escalation.

Vad Z-Index Exorcist ger dig

Byggd på djupet, så modulen faktiskt bär tyngden av riktigt klientarbete.

Stacking-context map

The invisible structure made visible: every stacking context, what creates it, and what lives inside it.

Conflict diagnosis

Why one element renders above another — the actual mechanics, not trial-and-error.

Kill the !important arms race

Fix the context instead of inflating the number. Your future self says thank you.
