Header usage should be hierarchical within page views Reference link: Standardize classnames and layout to facilitate theming
- Headers should be hierarchical, with two or more <h3> under each <h2> and so forth.
- <h2> is the top-level header of the page content/central column. There should be only one <h2>
- Headers should not be used for notification. Notification classes should be used for notification.
- We shouldn't even need the .main class, or any other additional classes used to alter the appearance of the header. The fact that the header is located in the central column/main content area, and is a header, should be enough. The only reason we need it is because we're recruiting headers for other purposes. Some cases, such as dimmed_text and other classes that are needed to allow for added functionality are an exception to this rule. The objective is to standardize the heading, without removing functionality for indicating an element won't be visible to students etc.
