Scroll to the right. Some exotic CSS thing that happens when your data URL is simply way too long. Fixed in Chrome with: .dataurl { word-wrap: break-word; white-space: inherit !important; } But that removes the scrolling altogether and replaces it with a box as tall as needed to support the data link. EDIT: Just came back from the article explaining how this is done. Very simple and very, very clever.
