this padding-top doesn't do anything - overwritten by later rules
some minor typos
this bit of css was missing compared to the example page

without it the toolbar doesn't have a background, so the next comment about the text not being legible doesn't make sense
some wording changes that the person I was working with found confusing
without this space the css displays inline rather than in a codeblock
