HTML5 has a whole bunch of content models not previously available.

• Header not required in HTML5.
  
• A header cannot contain another header or footer element.
• A header is not sectioning content.

Notes from class:

• Visual object lesson: Money! Which would you choose: 1000-peso bill from Mexico, $1 American bill, or a 2-peso bill from 1976?
• Envelopes to carry them in. But you can't tell which one is which. We need a way to refer to the envelopes: "Yoda," "Obiwan," and "Mace Windu."
• Value of this: You can change the values of each of the envelopes in one place, but you always have an envelope to refer to.
• Envelope = "variable" we can refer to.
• Learn about forms
• Something I learned: There is an input type "password" that lets you type something and it comes up as dots in the field so you can't see it!
• HTML is not case-sensitive.
• When you click on the submit button you create, the url changes.
• Any time you see a question mark, think "Variable!"
• In a POST method, you can't see the destination in the URL.
• In a GET method, you CAN see the destination in the URL.
