Section 3.5 Titles
Divisions always require titles, you accomplish this with a
<title> tag first thing. Almost everything that you can use in a paragraph can be used in a title, but a few constructions are banned, such as a displayed mathematical equation (for good reason). Try to avoid using footnotes in titles, even if we have tried to make them possible.Since titles migrate to other places, such as a Table of Contents, there are options for variants of a title, such as a short version, or a markup-free version. Some (major) titles may also be structured as a sequence of
<line> elements to control line-breaks for long titles.Many, many other structures admit titles. Experiment, or look at specific descriptions of the structure you are interested in. Titles are integral to PreTeXt, much like cross-references. Titles migrate to the Table of Contents, get used in page headers for print output, can be used in lists (such as a List of Figures), and can be used as the text of a cross-reference, instead of a number. You might be inclined to not give a
<remark> a title, but it would definitely be good practice to do so (study Best Practice 4.8.1). For more details consult Section 4.8.
