@andy_unleash : yea, I was a bit too quick with my comment. It’s too experimental it seems, so better not use it.
If I would have this issue myself, I would just give each LI a specific width though, so that it’s spaced exactly the way I want to.
Sure, some people would consider it a cop-out, but…..it would give me the result I’d be looking for. And you don’t have to cater to the people who insist on having a “cleverer” solution.
Or you could remove the widths from the LI’s and just give them all a padding of 26 or 27 pixels left/right. Problem is that browsers render it a little differently so it might wrap to the next line. In that case, set it to 25 pixels and center the UL a little more precise.
