Support Theme: Remove some excess whitespace on home page

[SergeyBiryukov]

In the ​preliminary mockups, there's enough breathing room between sections and items on home page, but in the current theme it seems a bit superfluous. On ​https://ru.wordpress.org/support/, we have 12 forums, and the list doesn't even fit on my desktop screen.

With that much whitespace, it's hard to focus on forum descriptions and find the right place to go.

I think we could keep enough breathing room, but remove some excess whitespace to make the page easier to parse.

I'm not sure I agree, that there is too much whitespace. There may have been changes to the homepage since this ticket was opened that helped, but I do think the way it's currently displayed is fine.

Let's not change it?

The only excessive bit is where the tag cloud used to be, but this will be solved by the introduction of HelpHub shortly, so this ticket can safely be closed in favor of that.

I still think removing some excess padding would improve the usability here. The current layout is just too difficult to scan, it doesn’t really look like a list of interactive forums at a glance, and people are mistaking it for an index of static content. See #4007 for some additional context.

Going to experiment with 2570.patch​ a bit.

Go for it, I believe the styles are re-used on the HelpHub part as well, so perhaps give that a look over after the fact so they aren't too mushed together.
