Persistent headings

The .lastheading {depth} docs ↗ function allows you to reference the last heading of a given depth across pages or slides.

When used in combination with page margin content, this function enables persistent headings, such as chapter titles or section names, to appear in the page margins.

depth refers to the heading level: 1 for #, 2 for ##, and so on.

Example 1

.pagemargin {topcenter}
    *.lastheading depth:{1}*

## Chapter 1

.repeat {10}
    .loremipsum
Persistent heading

Note that headings of lesser depth reset the last reference.

Example 2

In the following example, the depth-2 persistent heading appears when on a depth-2 section (page 2), but resets when entering a depth-1 section (page 3).

.pagemargin {topleft}
    *.lastheading depth:{1}*

.pagemargin {topright}
    *.lastheading depth:{2}*

## Chapter 1

.repeat {6}
    .loremipsum

### Subsection

.loremipsum

## Chapter 2

.repeat {2}
    .loremipsum
Reset
