Homepage bugs

-fixed a few button/link bugs - using link_to and button_to instead of HTML
-added arrows to the Value for Creator section
-added different background color to alternating sections
-added scrolling down the page when clicking first 2 buttons! :grinning: 

**Still need to work on responsive styling in the top section - when resizing the window, the header ("Build beautiful...") gets cuts off.  Any advice/help on this would be awesome!
