readability vs. legibility

Readability talks about large bodies of text, and is more the guidelines to making it easy to read this text. Legibility is more the construct of small, quick text and the rules thats apply to the varying ways people will view such text.

Typography is a set of rules and guidelines that follow how we can set up a website to make it readable and legible. It goes on to explain how computers are all essentially different in some degrees and ways to correct how someone will see this. These tools will become very helpful in creating my own site. There were many things that I would have never considered, someone not having a font  that I had and getting a default font loosing the purpose of using that said font.
