Question: What Is Z Index?

Why is Z Index not working?

TL;DR: the most common cause for z-index not working is not explicitly declaring a CSS position value (i.e.

position: relative, absolute, fixed or stick) on the element.

But if this hasn’t solved your z-index issue or just want to get a little more information about the CSS property, then let’s go a little deeper..

Can I use negative Z index?

You can have negative z-index To place an element on a layer below another one, it just has to have a lower value of z-index but that lower value can be negative. One area where this is useful is when using pseudo elements and wanting to position them behind the content of their parent element.

Is Z index relative to parent?

Afaik, z-index doesn’t work unless that element is set to position: relative; If that same element had a child with position: relative; and the z-index was set higher, the child would show on top of its parent. So it has elements of both ‘absolute’ and ‘relative’ stack order as you phrased it.

What is default Z index?

The default z-index value of all the elements on a web page is auto, which corresponds to 0 where no z-index is assigned. An element with z-index: -1 will be displayed behind all other elements on the page, assuming they are given no z-index values.

Can you transition Z index?

You can apply CSS3 transitions to the z-index property, but it may work in a way you don’t expect. This is just a reminder that you can apply transitions to an element’s z-index (aka, where it lays in the stack), but only by stepping through the layers. The browser has to keep z-index in whole numbers.

What is Z index in Web design?

What is highest 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.

The solution to this is to set position: relative and explicitly set z-index on at least the white block. You could go one step further and set position: relative and a lower z-index on the cat elements, just to be extra safe. In my opinion, doing this will solve most, if not all of the more basic z-index issues.
