The body of a sidebar block. This was made with the Custom Block Manager plugin.
About the Journal
The "About the Journal" section header, above, is automatically generated as an H1 heading.
Heading 2
The first heading I code myself, as a subdivision of the content under "About the Journal" should be an H2 heading. H2 is the first level in the hierarchy below H1.
Heading 3
Subdivisions of the content covered by "Heading 2" should be coded as an H3 heading. I could further subdivide it with H4, and that with H5, etc...
Another heading 2
The content here is another subdivision at the same level of hierarchy as "Heading 2."
