Comment 42 for bug 1512093

I just added this to media/css/documentation.css of the website:

th {
 background-color: #595959;
}

And used definition lists explained here: http://www.sphinx-doc.org/en/stable/rest.html#lists-and-quote-like-blocks (third example).

We should also rethink the css of <code> <pre> tags in the code. The Black background color isn't good to see.
