Search bar layout

This pull request addresses #2

I've gone through several iterations to get the functionality and responsiveness working correctly. Unfortunately I'm still not complete but the lacking responsive view is the one that we are still waiting to hear back on design. Will keep working on this, but I wanted to put it up to hopefully get some feedback.
