Consult with the A Beginner's Guide to HTML for more details on HTML headings. HTML headings are numbered 1 through 6, 1 having the most emphasis.
To set a selection of text as a specific heading, select it with the mouse, then choose the desired heading from the Heading menu. Alternately, place the insertion point into the text at the point you wish the heading to be placed, then choose the Heading level from the popUp menu. The start and end codes will be placed before and after the insertion point ΓÇô you may then begin typing the text.
Note that the shortcut Command-H will set the current selection of text to the current heading level, visible as "H1" through "H6" at the bottom right of the document window.
Note that it is forbidden by the official HTML and HTML+ specifications to imbed a heading within an anchor, nor should you use heading tags within a list (in order to obtain a larger font size).
To quote the NCSA HTML Primer,
"Although most browsers will currently handle this, it is forbidden by the official HTML and HTML+ specifications, and it will not work with future browsers... What's the difference? This is again a question of SGML. The semantic meaning of <H1> is that it's the main heading of a document and that it should be followed by the content of the document. A browser that formats <H1> as centered text on the page is likely to get confused if it finds that tag within a list. "
Choosing the Index command and a specific heading level returns a list of all occurrences of that heading within the document. To close the Index list, click on its close box. See also HTML Code Indexing.
Back to Anchor menu, on to Font menu, or return to Contents.
