Add background color to images
If an image is loading on a slow connection, it displays progressively
and there's a large blank region where the image will be. Giving it a
background color makes the eventual shape of the image display more
clearly.

Minify inline CSS, move syntax colors to bottom of page
This improves both maintainability and performance because the CSS
can be written out-of-line, and then get inserted and minified.
The stylesheet tag for the syntax colors got moved to the bottom of
the page, because CSS in the head tag blocks rendering until it's
loaded. Inside the body is dependent on browsers, but they all support
it and in the worst case you just get the original blocking behavior.
