Out of curiosity, I wanted to know what the maximum z-index is. The CSS 2.1 spec doesn&#x27;t present this information, but it turns out to be 2147483647 (the maximum value for a 32-bit integer).<p>Now what does that z-index say about the JavaScript developer who chose it? &quot;Fuck it, 999999 is enough.&quot; Man, what a tool.
