Standardizes colors, header

[jessicaschilling]

• Adds IPFS logo (link) to header
• Standardizes colors and fonts
• Minor visual tweaks

Closes #31
Closes #254

Note: This is more of a "triage" fix than full CSS refactoring of the dist site; the intent is to take something that was pretty much unbranded and at least bring it into line with base colors, fonts etc. There are plenty of visual fixes that weren't made, but hopefully nothing is worse.

@dignifiedquire -- took a stab at an old issue. Can you please have a look and recommend any additional reviewers who should examine? Thank you!

We should check the fonts in, but that's not a regression.

The jq dependency is breaking the build on my machine (transitive dependency contextify doesn't build).

[Stebalien]

The jq you're installing is not the jq you think you're installing.

@Stebalien Thanks for the reminder, totally forgot to uninstall that.

Fixed.

[Stebalien]

Oh my, that looks SO much better!

@hsanjuan Do you mind a quick look, at @Stebalien's recommendation? Thanks!

The menu offsets aren't quite right. When I scroll to the bottom, it still doesn't focus ipget. It should probably switch focus once both the header of the previous section scrolls off the screen (no idea how to actually implement that).

First THIS IS SO MUCH BETTER JESSICA!! Awesome. 🎉

Re #289 (comment), what I see is that jumping to "ipfs-update" actually just focuses ipget. (still weird)

Could we also tighten the padding on mobile:

I want the CTA of clicking the "Download go-ipfs" button to be really clear - so making that a little bigger/brighter/bolder would be nice - maybe 18px?

• brightens hover states
• bigger button text
• tightens mobile layout
