Sorry i thought i should ask this here as apposed to your CSS site as ive a feeling its something that Drupal is doing and not just a general css question.
When viewing the last comment time on the right of the main table of this page (and taxonony table pages) you will see that something is adding an tag to my date field. My site with the em added
The norm12 span class is what i have added and you can see that even making the font-style: normal with important added its still showing it with tags and style about it.
Its only a minor problem but its driving me mad.
Can anyone see where the problem may lie?
