Open Content Licensing/Layout and design

Headers
Each page begins with introductory text. We recommend the use of level 2 headers as a way to organise the text on the page, but a header should not be positioned as the first element on a page.

Check list

 * 1) Check that each page uses a CC-BY license -- if not add    at the bottom of the page
 * 2) Ensure that each page uses the green previous next buttons (Example at the bottom of this page).
