🎨 CSS Isolation Explorer

Interactive tool for CSS isolation, mix-blend-mode, and stacking contexts

⚡ Isolation: isolate vs auto

0.85
isolation: auto
isolation: isolate
How it works: With isolation: auto (left), child elements blend with everything behind them, including the page background. With isolation: isolate (right), a new stacking context is created — children only blend within their parent container.

Sibling (z:3)






Stacking Context: When a parent has isolation: isolate, it creates a new stacking context. Its children's z-index values are scoped within the parent — they cannot escape above or below elements outside the parent's context, regardless of their z-index value.
