We hadn't added this rule before because there was no such rule in
scss-lint. Instead, we were following it without a linter, and so we
unintentionally broke it sometimes.
But now we're using Stylelint, so we can add the rule and let the linter
check we're still following it.
We were displaying the alt text using the same color as the background
color, which made it impossible to read it when the logo didn't load
(for whatever reason).
Using the same color as the text, like done in the admin section, solves
the issue.
The top bar padding was different on small screens when we were in the
admin section, so we're now applying the same padding everywhere.
Note we're still applying extra padding on medium/large screens because
in the public section we display our logo image, which has some blank
space. In the admin section we're emulating this blank space with
padding; we might change it in the future if we change our logo.
Also note we're using `0.8rem` instead of `$line-height / 2`. The reason
is tricky: there's a spec testing the reorder feature with drag and drop
in the poll questions answers administration, and that test fails when
the drop space is right at the bottom of the screen, which is what
happens when we use the `$line-height / 2` padding. A proper solution
would be to remove the inaccessible drag and drop feature and use a
different method to reorder the answers.
So now it uses the same interface and styles as the main layout. On
small screens, it's easier to play with the menu when the button is on
the left because the menu it opens is aligned to the left.
Note that now we can get rid of the title-bar class; we didn't use the
styles in the public area since commit dcec003d0, and we were overriding
all the Foundation styles in the admin area with the exception of the
padding, which we no longer need.
We're going to change these styles in order to fix a bug, and the
Foundation styles were getting in the way. Besides, we were overwriting
some rules and so now we're removing 6 properties while we're also
adding 6, so it isn't like the Foundation styles were helping us.
This class was only there in order to use Foundation's styles, but
the amount of styles we were using was equal to the amount of
styles we were overwriting.
This way it's easier to refactor it.
Note we're using `with_request_url` in the tests because the component
renders the locale switcher, which needs a URL in order to work. This
doesn't affect whether we're in the management section or not.
