should this be .settings-box.two-line?

[scottchen, 2016/11/03 19:26:22]

You're right, I missed the fact that there are other things using the .two-line
class.

I'll revert this .two-line rule to use the previous setting, and then add a
separate .settings-box.two-line rule.

[scottchen, 2016/11/03 22:15:48]

Done.
