It was probably a cache issue. I've found when editing sitewide css my browser won't see the changes unless I do a "hard" refresh. And especially if you clicked the edit button on the page in one tab, edited the CSS in another, and then went back to the first tab, your browser probably retrieved the old version of the CSS page when the tab first loaded, and didn't recheck it when you hit the preview button.
