HTML Intro

Things I want To Learn-

1. I want to learn more about how the beginning of a sentence effects the way it shows up in the paragraph. 
2. Can this format be used to make things other than sentences?
3. How has this affected typing?

Things I Leaned-

1. I learned that the beginning code is held in < >s
2. You type in the code and then press see results to see what you have done. 

Thing I'm Concerned About-

1. Why can't you just type regular words in order to make a webpage, why does it have to be in HTML format?
