How do I hide an element with Z-index?
Some other ways to hide elements
- Use z-index property. #element { z-index: -11111; }
- Move an element off the page. #element { position: absolute; top: -9999em; left: -9999em; }
Why my Z-index is not working?
If you set position to other value than static but your element’s z-index still doesn’t seem to work, it may be that some parent element has z-index set. The stacking contexts have hierarchy, and each stacking context is considered in the stacking order of the parent’s stacking context.
What is Z-Index 9999?
CSS layer refer to applying z-index property to element that overlap to another element. CSS z-index property always work with absolute as well as relative positioning value. CSS z-index possible value 0, positive (1 to 9999) and negative (-1 to -9999) value to set an element.
What is Z-index in Javascript?

What is the difference between display none and visibility hidden?
display:none means that the tag in question will not appear on the page at all (although you can still interact with it through the dom). There will be no space allocated for it between the other tags. visibility:hidden means that unlike display:none, the tag is not visible, but space is allocated for it on the page.
Does visibility hidden affect performance?
When you are animating with the dom at around 20 times per second THEN you can worry about the performance of visibility:hidden vs display:none. visibility: hidden does not cause a re-flow on the document, while display: none does.
Does Z-Index work without position?
Yes: use position:relative; z-index:10 . z-index has no effect for position:static (the default).
Why Z-index is used in CSS?

What is the highest Z index?
2147483647
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.
What is Zindex?

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.
What should I do if my z index is not working?
To sum up, most issues with z-index can be solved by following these two guidelines: Check that the elements have their position set and z-index numbers in the correct order. Make sure that you don’t have parent elements limiting the z-index level of their children.
Where is the z index on the side tab?
All the elements have their position set, and the side tab has a z-index of 5, which positions it on top of the content element, which is at z-index: 1. Then, the modal has z-index: 100 which should put it on top of the side tab at z-index: 5. But instead, the modal overlay is underneath the side tab. Why is this happening?
