Text & Links
Blogs are all about text content so make sure it is easy to read. Use a sans-serif font with a minimum font size of 16px, color black on a slightly off white background - somewhere between # FEFEFE and #F8F8F8. The slight reduction of the background's "whiteness" helps to reduce glare and makes for more comfortable reading.
Avoid using colors - and never use pale colors - except for spans and links.
The font used here is the Google hosted "Stint Ultra Expanded" with the fallback font set to "helvetica". Always provide a web safe fallback font when using a non web safe or hosted font. The font is not very robust so the paragraph font size is increased to 18px.
Spans
Use spans with keywords to break up large chunks of text and help the search engines understand the key points. Follow the link below to find out about creating <span> tags. Most of the EverWeb Widgets that have fields for large text blocks have basic styling for span size and color.
Links
Items like bold text and text links have no place in modern web design. The use of these is a throw back to the bad old days before CSS was invented.
If extra links are required, use CTA style links like the "Quick Links" shown below. Visitors are more likely to follow a link if it is isolated, is big enough for finger tapping on touch devices and has interesting and relevant text.
