Due to some some backend changes, we've updated how themes work on the site. If your old theme was lost, not to worry -- it can be recreated in two easy steps:
1) To change the theme color, scroll to the bottom of the page, click "themes" and choose your theme color (light or dark). The page will refresh
2) To change the font size and screen width, click "change font-size." (The large and X-Large font sizes expand the page width.)
Please let us know if you run into any issues.
Thank you!
