Convert project gallery from 1000px to 970px

[caleybrock]

The header for this isn't perfect, but I think we should consider updating the HeadingBanner in a separate PR once /courses and /home is done because it'll affect other pages.

By header isn't perfect do you mean the component with the "My Projects" and "Public Gallery" tabs?

[tanyaparker]

Or did you mean the "Project Gallery" title doesn't left align with the rest of the page components?

[caleybrock]

@tanyaparker yep, those were made for 960px (which I'm not sure what matches) so it doesn't line up perfectly.

[caleybrock]

@tanyaparker the "Project Gallery" and the tabs are in one component, so those line up, they are just slightly off with the rest of the page.

Code changes look good.

Seems to me like it would it be better to left-align Playlab, Artist etc. with Projects Gallery and the gallery switcher, however I'll let you all decide how it should look:

Please make sure you also look at this:

• with the My Projects tab selected
• while signed out

Great suggestions, Dave. +1

[caleybrock]

Good call. I updated that with the expectation that we may have to adjust a bit again.

This looks better! Thanks for changing.
