Changes in the layout from alabaster v0.7.16 to alabaster v1.0.0

[ronald-jaepel]

Dear Alabaster Team,

this isn't really a bug report, more of a hickup-report as an Alabaster user that I wanted to share so that other people googling for this issue might find a quick solution.

We just noticed the formatting for our documentation was wrong, but didn't know if it was a change in Sphinx or in Alabaster. Tables and TOCs were displayed incorrectly, figures suddenly spanned far beyond the width of the screen. After a bit of search the difference stemmed from the removal of @import url("basic.css"); in alabaster.css. After adding @import '../basic.css'; to our custom.css things look nice again.

Maybe this can speed up the debugging process for someone else.
Best wishes.
