Comment 2 for bug 1760160

I took a look at this, and agree that being able to adjust the style of the search bar based on whether or not the user is at the home page is a good idea. However, I have a suggestion: rather than defining separate styles for the input and the submit button, how about instead having it add a searchbar-home (or whatever) class to the div enclosing the entire search bar? That would open up more options for styling every child element without needing to add more classes.
