z-index is something that can measure one's frustration. The amount of digits represent the fact that the developer tried to position the
div above the content, but failed miserably.
What is the problem and how to fix it
z-indexcan only be used with
positions. In my example, this line is missing.
z-indexhas a maximum value which is 2147483648, the maximum positive value for a 32-bit signed binary integer in computing (the example has +2 digits).
- If you don't change anything on your content's z-axis value, adding 2 or 3 has the same effect as 100 or 10000. Adding huge numbers can lead to hard maintainability.
- You might not even need
z-indexat all, just push your DOM element a bit further towards your
</body>tag, it will be rendered later than the elements in the same layer preceding it, so it can cover them.
