Headings follow a six-level hierarchy, starting at 1 and ending at 6. The level of the heading is defined by the number of equals signs on each side of the title. Heading 1 ( = Heading 1 = ) is automatically generated as the title of the article, and is never appropriate within the body of an article.
Sections are created by creating their headings, as below. These are sometimes called "levels" based on the number of equal signs before and after, so that the top "Section" above with two equal signs is a "level two" heading, the subsection is a "level three" heading, and the "sub-subsection" is "level four".
Headings are hierarchical. The article's title uses a level 1 heading, so you should start with a level 2 heading (==Heading==) and follow it with lower levels: ===Subheading===, ====Subsubheading====, and so forth. Whether extensive subtopics should be kept on one page or moved to individual pages is a matter of personal judgment.
The heading must be on its own line, with one blank line just before it; a blank line just after is optional and ignored (but do not use two blank lines, before or after, because that will add unwanted visible space). For technical reasons, section headings should: Be unique within a page, so that section links lead to the right place.
A table of contents usually includes the titles or descriptions of first-level headings (chapters in longer works), and often includes second-level headings (sections or A-heads) within the chapters as well, and occasionally even includes third-level headings (subsections or B-heads) within the sections as well. The depth of detail in tables of ...
h1 delimits the highest-level heading, h2 the next level down (sub-section), h3 for a level below that, and so on to h6. They are sometimes referred to collectively as hn tags, n meaning any of the available heading levels. Most visual browsers show headings as large bold text by default, though this can be overridden with CSS.
Headings and subheadings can be added by clicking Advanced then Heading in the extra toolbar line which now appears. Selecting "Level 2" will format text as a main heading, the most frequently used subdivision of any page. "Level 3" gives you a subheading for a Level 2 heading, and so on.
Some call the Roman numerals "A-heads" (for "A-level headings"), the upper-case letters, "B-heads", and so on. Some writers also prefer to insert a blank line between the A-heads and B-heads, while often keeping the B-heads and C-heads together.
