Quick CSS tip – width working in IE but not Firefox?

June 8th, 2010 admin

Just noticed a quick flaw which works with IE but not Firefox.   I had a table where I was specifying the width.   This was working fine in IE, but strangely Firefox was ignoring the width and scaling the table to match the width of the contents?

Turns  out I was specifying the width as an integer without appending “px”.    So width=100 tells IE to use 100 pixel width but Firefox ignores it.    Change it to “width=100px” and both are happy…

Links not working in Firefox

Here’s a good description of how to use z-index:
