Default CSS headers

[Nebucatnetzer]

I noticed that the headings sizes aren't correlating to the content.
E.g. an h5 heading is smaller than the caption of a table.
Since we should start with h2 the headers should be a bit bigger to not get so small when we use h5 as a level 4 heading.

Here is what github does:

Heading 1

Heading 2

Heading 3

Heading 4

Heading 5

Heading 6

So it seems that GitHub does get smaller and smaller headings, eventually smaller than regular text.

Since we should start with h2 the headers should be a bit bigger to not get so small when we use h5 as a level 4 heading.

I'm not sure I've ever had 4 levels of in-manuscript levels. When we're back from holidays, @vincerubinetti can perhaps suggest where to change the CSS to increase the level 5 heading size and see if he has any style suggestions.

The 4 levels happen because we had to use the project management phases in the document, otherwise 3 levels would be enough.
Smaller than the body text might be okay, what I find strange is that they are smaller than the captions which are usually footnote size?

It is built into HTML/CSS itself, and is not related to Github specifically. It is a long-standing default styling, which I happen to think was a stupid choice. I'd be happy to break with precedence in this case.
