How can I create a new stacking context using CSS properties?

Asked on Oct 15, 2025

Answer

Creating a new stacking context in CSS is essential for managing the z-index of elements. You can achieve this by using certain CSS properties that inherently create a new stacking context.

Example Concept: A new stacking context can be created by setting specific CSS properties on an element. These include setting a position value other than "static" and a z-index value other than "auto", using a CSS transform, setting opacity to a value less than 1, or using CSS filters. Each of these properties triggers the creation of a new stacking context, which isolates the element and its children from the rest of the page's stacking order.

Additional Comment:

Setting "position: relative" or "position: absolute" with a "z-index" other than "auto" creates a new stacking context.
Using "transform: translate(0)" or any transform function creates a new stacking context.
Applying "opacity: 0.99" or any value less than 1 will also create a new stacking context.
CSS properties like "filter" and "clip-path" can also establish a new stacking context.
