Why does my Z-Index not work?
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 Z-Index work without position?

Why is my position absolute not working?
If you are placing an element with absolute position, you need the base element to have a position value other than the default value. In your case if you change the position value of the parent div to ‘relative’ you can fix the issue.
Can you have negative Z-index?
You can have negative z-index This often means layering elements on top of each other, with ever-increasing values of z-index . Due to the way stacking context works, a negative value of z-index is needed on any :before or :after elements if they are to be positioned behind the text content of their parent element.
What is default Z-index?

Why is the tab index not working correctly?
The problem is that when I run the applicataion and cycle through the controls using the tab key, the tab index is not being followed. The last control that is selected is the check box.

What to do if your z index is not working?
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.
Why are elements on top when there is no z index?
Even if elements don’t have their z-index set, there is a rhyme and reason to which ones will be on top. In our case, none of the elements have a z-index value. So their stacking order is determined by their order of appearance. According to this rule, elements that come later in the markup will be on top of elements that come before them.
When to use iferror instead of index and match?
Note: If you want either the INDEX or MATCH function to return a meaningful value instead of #N/A, use the IFERROR function and then nest the INDEX and MATCH functions within that function. Replacing #N/A with your own value only identifies the error, but does not resolve it.
