Can CSS 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.
What happens when you assign a negative Z index value to an element?
Setting negative z-index (< 0) to an element will stack the element behind its parent. However, if the parent is the root element of a stacking context, creates the default stacking context, a negative z-index will still stack in front of the parent element.
