Twenty Fifteen: Multisite forms

[pavelevap]

Multisite registration forms do not look very good...

[lancewillett]

Hi pavelevap, can you review the other default themes from Twenty Ten to Fourteen also please? I don't think we've accounted for these forms in any of the previous themes specifically.

[pavelevap]

Yes, I asked for Twenty Twelve myself: #22179

There was support in Twenty Thirteen: #23631

There was support in Twenty Fourteen: #25479

Basic support should be available (forms, messages) for default themes, I guess.

This patch should get the ball rolling. It fixes the layout widths and padding for .mu_register on all screens.

[valendesigns]

This second patch uses margins for layout and adds a white background and padding inside the container to mimic article styles. It looks much better, and is how I should have done it the first time.

Cheers,
Derek

Twenty Fifteen: add styles for multisite registration forms.

Props valendesigns, fixes #30776.

Noted by @iamtakashi that needs a bit more work, including Registration page.

[iamtakashi]

Yes. There are still a quite few elements that are left as default and not harmonic with the theme style. We also need to pay more attention to responsive styles, typography, and old IEs. I'm working on a patch.

[iamtakashi]

Style properly multisite forms and pages to follow the theme style.
