creating Custom CSS for index page

Site URL: http://rewardkid.art/art

I have two questions. 

1) I'm trying to get the search to only show the page that is searched for (via tags, or words on that page). As it stands now, If I search orange, I get the image of that orange but not the page in the search?

2) is there a way to create in a second navigation bar a filter option which I could then filter what's shown on the art page? like, filter sports, and then on pages with a sports #tag appear?
 

I'm using the avenues theme. 
 

Thanks
