The background should be white.
Stylesheet "b" imported 30 times.
1 - 30:
#independent {background: green;}
31:

32:

33 - 43:

Stylesheet "c" imported 1 time, last.
1 - 30:
#independent {background: green;}

Here 44 @imports are in stylesheet "b" and "c", importing a number of small stylesheets
that only set the background-color for the test above.
– Stylesheet "b" is imported 30 times in the page-head.
– Stylesheet "c" is imported once, as 31.
What this @import branching test shows is that IE/win can handle as many as 31 imports in a series, in pagehead or in external stylesheets, but not a single import beyond that in one series.
Other browsers have no such limitation on numbers, but it takes time to fetch so many stylesheets.
