What position values will work with Z-index?

Note: z-index only works on positioned elements (position: absolute, position: relative, position: fixed, or position: sticky) and flex items (elements that are direct children of display:flex elements).

Is there a limit to Z-index?

The maximum range is ±2147483647. In CSS code bases, you’ll often see z-index values of 999, 9999 or 99999. This is a perhaps lazy way to ensure that the element is always on top. It can lead to problems down the road when multiple elements need to be on top.

How does HTML Z Index work?

The z-index property determines the stack level of an HTML element. The “stack level” refers to the element’s position on the Z axis (as opposed to the X axis or Y axis). A higher value means the element will be closer to the top of the stacking order. This stacking order runs perpendicular to the display, or viewport.

How do you avoid Z index?


  1. Understand how stacking works, and use the rules to your advantage to avoid using z-index , as long as it makes sense.
  2. Keep z-index values low: you’ll rarely need more than z-index: 1 (or less than z-index: -1 )
  3. Create stacking contexts to keep things boxed and prevent them from interfering with each other.

How do you overlap elements in Flexbox?

I include the :hover rule just to show how you could fully display a card from the middle of the “stack”, but in a real project I’d probably do this for selected cards instead of hovered ones.

Is Z index relative to parent?

The parent has a z-index of 2 and the child element also has a z-index of 2 . Because both parents create a stacking context, the z-index of all children is based on that of their parent. The z-index of elements inside of a stacking context are always relative to the parent’s current order in its own stacking context.

What is Z index used for in CSS?
