One issue I keep seeing pop up with this style is the top Google "Search Calendar" bar. Every so often, the class that controls the background color of that area will simply change. They have this really odd class scheme too, which makes it hard to understand.

What this means for you as the user is that if you see this happen, you can either wait a few days for me to fix it (assuming that everyone gets the same change at the same time, and with a company as big as Google who knows), or if yours is different than mine for some reason, you can make a pull request in my repo https://github.com/zposten/stylish, or you can send me a message with the class name that you need added to the list.

The list is currently the following. Note the odd, seemingly random pattern of letters.

#gb .gb_ve,
#gb .gb_re,
