Let's go over a simple way to organize your content on the page:
The page header is the title to your page. This is also referred to as Header 1. Because it is used as the title, there can only be one Header 1 per page.
The page is then broken down into sections, with titles for each of those sections. The titles to these sections are called headings. Headings start with the most general and overarching title, Heading 1 (h1), and go down to the most specific, Heading 6 (h6). Again, there can only be one h1, but you can have as many of the others as you like. When writing titles and subtitles, keep in mind that they should be a clear and concise summation of the content that follows.
Headings should always follow a clear order. Say, for example, you have a page called "Facts & Figures" that is broken into three sections called "The Academic Program," "The People," and "The Place." And "The People" is broken into three subsections called "Students," "Student Honors Earned," and "Faculty." Your page should be organized like this:
As you'll notice, any subsection that sits under a Heading 2 is a Heading 3. Let's say we add two subsections to each Heading 3 item. The page would then look like this:
The above title is created by selecting Heading 2 from the format dropdown in the WYSIWYG. The Sub Title Header provides an easy way to break your page up into Sub Sections.
The above title is created by selecting Heading 3 from the format dropdown in the WYSIWYG. The Third Level Header is used to separate sub sections with a clear sense of hierarchy within a Sub Section.
The above title is created by selecting Heading 4 from the format dropdown in the WYSIWYG. The Fourth Level Header provides yet another level to help break a page up into easily digested sections.
