Z-index

Z-index utilities change the stacking order of positioned elements: z-n1 sends an element behind its context, z-0 creates a base layer and z-1, z-2 and z-3 bring elements forward. They only apply to elements with a position, so pair them with position-relative or position-absolute.

1Z-index scale

z-n1, z-0, z-1, z-2 and z-3 stack positioned elements from back to front.

z-3
z-2
z-1
z-0
z-n1

2Order without z-index

Without z-index, later elements paint on top of earlier ones.

first
second (on top)

3Bring the first one forward

z-1 on the first element puts it above its later sibling.

first, z-1
second

4Background shape behind content

z-n1 places a decorative shape behind the text of its positioned parent, which uses z-0 to form a stacking context.

5Overlapping avatars

Decreasing z-index keeps the first avatar on top of the stack.
