How very random.
I’ve just completed a website redesign and uploaded the files onto the new server, tidied up some of the code, tested and checked that my css was working correctly. during this process I find that my background image is peaking out below the footer image causing a silly white block at the bottom of my page. This was only in IE; firefox and Safari were fine.
After a line by line check between the working build page and the faulty page I noticed a single difference – the position of a comment.
Correct page looked like this
Faulty page looked like this
Who would have thought a simple comment placement could have made so much difference.
