So from my understanding of reading the book, an in line style has the highest priority while a tag selector is not very powerful, but you can selectively override a certain element if necessary. An ID selector is powerful and hard to override therefore many web designer avoid them. Each browser uses different properties subtle differences. Usually it’s a good idea to start a clean style sheet by removing padding and margins.
Some other things that I noticed while created the different page is that I need to pay attention to all the element in a page. I had it the way I wanted and then I changed fonts which changed the placing to different things which I failed to see. It probably would have been a good idea to take the second typography class.
