Finishing up the styling

EDIT 3/22

• breakpoints - mobile friendly
• mobile - push what's not here as the last box? (see #345 (closed))
• Update style: #227 (comment 80275)
• whitespace: #300 (closed)
• different font options for titles of blocks
• slightly smaller font size for results

To-do abstracted from Nathan V's recent feedback.

• Remove anchor links
• Drop white background from (class "1-main"?) behind boxes, leaving gray space on which white-backgrounded boxes sit. (moved to #336 (closed))
• Separate sidebar boxes - @bzk60
• Rearrange results fields to match Nathan V's layout here: https://psu.app.box.com/file/294471479523 (but put Type on the right, in order to allow for multiple types)
• In Books & Media, comment out location field until we can figure out best way to display it - @bzk60
• See images below for Articles, Books, News, Website. Match except for bottom section/link to results (leave that as is).
• Square off sidebar and "What's Not Here" to match the square blocks below.
• Change sidebar and "What's Not Here" header text to same font as blocks below (only change font, not contrast)
• Availability dot colors: available = green, in process = orange, ill = blue, checked out = red
