Print stylesheet

[srittau]

I'm getting old. When reading through or reviewing things, I like to sit in a comfortable chair with coffee or tea, hold a stack of A4 paper with a large font (who needs trees anyway?) and a marker, instead of reading on a tablet (or - horror - my phone). This is what a printed PEP looks like at the moment:

I suggest to add some print styles to the PEPs with the following properties:

• Remove the top bar.
• Remove the table of contents side bar.
• (Optional) Expand the table of content by default. (If that's possible with pure CSS, I haven't investigated.)
• Slightly tweak the font sizes, especially smaller header sizes, possibly centering the main title.

If there's interest, I could prepare a PR.

Sounds reasonable to me, who doesn't like a nice cup of tea and a comfy chair.

It could also remove the light/dark theme button at the top right.

It could also remove the light/dark theme button at the top right.

I think removing the entire top bar is the proposal, which would cover this as well.
