After reworking three web pages, I am seeing certain CSS content that is the same across all pages. I have moved this into a central CSS file that is now included in all site pages. Each page also includes a local CSS file with stylization that is specific to that page. The central page now includes a background image and a font specification.
Changing the font really helps make the page look less like a relic from the 1990s. After doing some reading, I decided to use Google Web Fonts rather than including font data files on my site. I am not that particular and think the Merriweather font looks fine, so I chose that. Not having to maintain the font data is very appealing to me, and the load time still seems reasonable.
