When a code block has more than one digit in its line numbers, the display in the docs currently breaks for Google Chrome 22.0.1229.94 under Ubuntu 12.10:

The issue can be fixed by increasing thewidth oftd.linenos from35px to36px. Themin-width should probably be adjusted too.

With three digit line numbers, the display breaks again. The minimumwidth that works here for "999" is44px.

On a related note: YAML and XML snippets are missing line numbers.
