I am trying to edit the CSS for my blog and am currently using the Digg 3 theme. Whenever I enter new coding and preview, the page tabs on top of the header disappear, along with the rounded corner borders around the sidebars and post entries. Any idea why this is happening? To my knowledge I didn’t change any coding for the .page CSS or the header.
I haven’t noticed this often, but when you “preview CSS”, it adds the black bar that adjusts the way the theme looks and on a couple of designs I have used, it isn’t “exactly” the way the theme is displayed because of that black bar in the preview. Not much help, but maybe an explanation. If you save your current CSS sheet (in a text editor) and apply the changes you can look at it quickly live and still go back to that original sheet from the text editor if it isn’t correct :)
