If you’re playing fast and loose with the stylesheet.

Make sure you check the page in at least one other browser.I usually do except sometimes even miss perfect forgets.
A day ago I was all like look at my version of a tables-less css gallery! and then I checked it in internet explorer and my wacky padding hijinks had all my content overlapping,obscuring other content, running down the center of the page in a thin strip…in short a total mess.And it was so nice in firefox,too. sigh. I fixed it.
