Mobile device notes:

• [x] Be sure to account for the "hover" effect on the home page. This is not very friendly towards mobile devices.
• [x] links should be bold, on click change background color
• [x] headings should be normal font size but different color—use a strong accent color see another issue for headings altogether
• [x] add <meta name="viewport" content="width=device-width, initial-scale=1"/> to all pages
