The Oasis search isn't part of the Wikiamobile skin, unless viewing the "full site".

It might just be me, but if you can do it with system messages, do it with system messages. If not try CSS. Then, as a last resort, use js/jQuery. This wasn't always an option when there was not common support for some CSS properties/pseudo-classes in older browsers (yes, we're looking at you IE6) but the worst browser Wikia supports now is IE9 which only doesn't support the CSS still in Candidate Recommendation iirc.
