Search Plugin

1) I’m trying to do a search box that is horizontal and includes the location taxonomy, which doesn’t seem to be available to be used by the widget.

Can you help me with CSS for those things?

2) I also was hoping someone could help point me in the direction as far as how I can make the search boxes wider and change the look and size of the submit button of the search?
