Hi Simon,
I'm super excited about this! Good luck.
I took a quick peek and noticed that you have both a `cssparser.rc` and
`cssparser.rs`. This pattern is more or less deprecated, a relic from a
time when `rc` files had a special syntax (I'm assuming you copied this
pattern from some of the other servo submodules that were ported forward
from older language revisions). I would recommend putting the content of
`cssparser.rs` directly in `cssparser.rc`. Some background on this
topic:
