Header and footer

Company logo, event name, “Confidential”, page number: instead of repeating them on every slide, write them once with @header and @footer. Folio places that content in the same spot on every slide, except the cover.

The basics

Write the block at the start of the presentation, next to @title and @theme, and close it with @end:

@title 2027 Plan
@theme paper

@footer
2027 Plan · Confidential
@end

# 2027 Plan

---
# Where we are

---
# Where we are going

The first slide is the cover and has no footer. On the others, the footer sits at the bottom, inside the slide margin.

The content between @footer and @end uses the same language as the slides: text, images, icons, styles, components and blocks such as ::: columns.

Left and right

To put one part on each side, use ::: columns. Each item becomes a column, so separate the items with a blank line:

@title Lumen Pitch
@theme ink

@header
::: columns {valign=center}
:: icon rocket {size=lg color=accent}

Lumen Analytics {align=right}
:::
@end

@footer
::: columns
Confidential

$page / $pages {align=right}
:::
@end

# Lumen Analytics

---
# Traction

Tip

Two consecutive lines without a blank line between them form a single paragraph with a line break. That is why they would stay together, in the same column.

Automatic fields

Inside @header and @footer, these fields are filled in on each slide:

Field	Becomes
$page	the slide number (the cover counts as 1)
$pages	the total number of slides
$title	the presentation’s @title
$author	the presentation’s @author
$date	today’s date, in the viewer’s language

A misspelled field shows up as an error, with the closest match suggested: $pagina suggests $page.

Appearance

By default, header and footer use small text (size=sm) in the theme’s muted color. On a dark slide, the color follows the slide.

To change the default, put attributes on the @header or @footer line. They apply to the whole block:

@theme paper

@footer {align=center color=accent weight=bold}
Product Week 2026
@end

# Opening

---
# Agenda

Attributes inside the block still work as usual, such as {align=right} on a paragraph.

Cover and exceptions

The cover has no header or footer. By default, the cover is the first slide. On each slide’s --- line, you can change that:

On the --- line	Effect
{cover}	the slide becomes a cover too, with no header or footer (good for section slides)
{cover=false}	the first slide stops being a cover
{footer=off}	removes the footer from this slide only
{header=off}	removes the header from this slide only
{footer=on}	shows the footer even on a cover

--- {cover}
# Part 2: Results

--- {footer=off}

In the project theme

A @header or @footer written in the project theme applies to every presentation in the project. It is the place for the company’s standard footer.

• If a presentation has its own @footer, it replaces the theme’s.
• To remove the theme’s footer from one presentation, write @footer none.

@title A presentation without the company footer
@footer none

Under the hood

Header and footer take a reserved band: slide content never ends up underneath them. A one-line footer fits inside the theme’s margin and does not change the layout. If the block is taller, the content area shrinks.

A few things do not apply inside @header and @footer:

• Step-by-step reveal. Header and footer are always shown in full; step and ::: steps are ignored, with a warning.
• Speaker notes. ::: notes inside the block is ignored, with a warning. Write notes on the slide itself.
