After I changed themes early today, I’ve been checking blogs and websites in an effort to find a fix for my new design’s bug – its inability to be displayed properly in Internet Explorer.
Until this afternoon – Explorer displayed only one column of the two-column sidebar. The third column was displayed under the second bar. I took all my sidebar elements out and placed it back again one by one – shoutbox, recent comments script, buttons etc. and found that I deleted one unordered list closing tag. After fixing this, Explorer finally rendered the homepage design properly. And then I checked the individual page for the posts – its layout was horribly wrong under Explorer.
Thanks to Yuga’s tip below, I decided to look for the code that defined the width of the sidebar and changed it from 320px to 310px. That fixed everything – the homepage and the individual item pages.
