Second issue: <code> block in a <pre> element.

Third issue: One of my old browsers uses the standard serif font
to format the <code> block, because in a file named 
hightlight-js.css
font-family is reported to be "unset".

Fourth issue: Please use lokal URL as much as possible:

https://forum.dlang.org/font-awesome/4.4.0/css/font-awesome.min.css

instead of

https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css

I strongly dislike those data transmissions to third parties as
