First of all thank you very much for the new interwiki search feature. It is great :-)

Second, I think the header of the interwiki search result "Showing results from xxx Wikipedia." should be styled a bit so that there is an optical accentuation that the following search results are coming from a foreign wiki/are in another language.

I know that his can be done via the local Common.css (*) but it would be better to have a consistent styling for all projects.

(*) Me and another Wikipedian have styled it on dewiki, see this example. This styling is not the best and critized by other Wikipedians with good reasons.
