If you want a heading that doesn a new slide, like this

Level-3 Heading!

Just use html heading!

<h3>Level-3 Heading!</h3>

Force starting a new slide

If you want to start a new slide without headings.

Just use the markdown horizontal break ---, like this

---

Force starting a new slide!

Include Files

include files normally

./included.md

More details: https://github.com/pandoc/lua-filters/blob/master/include-files/include-files.lua

include files in code block

``` {include="./helloworld.c"}
```

More details: https://github.com/pandoc/lua-filters/blob/master/include-code-files/include-code-files.lua

example: Chart.js

::: {.container} :::: {.col}

include a chart.js plot

``` {.include}
./plots/chartjs.html
```

:::: :::: {.col}

./plots/chartjs.html

:::: :::

example: Plotly.py

::: {.container} :::: {.col}

include a plotly.py plot

``` {.include}

Label and Link {#label_and_link}

You can label a slide by adding a name to its heading

# Label and Link {#label_and_link}

Link

Then you can go back to the labeled slide ⬆️ Label and Link⬆️ .

[Label and Link](#label_and_link)

Localization (Offline mode)

Long Table

Bother by long table?

::: {.fragment} Then use wrap your long table

with [.longtable]{style="font-size:1.5em;"} like below

::: {.longtable style="height: 300px;"}
<your long table here>
:::

:::

Example

::: {.longtable style="height: 500px;"}

This	is	a	long	vertical	table
1	2	3	4	5	6
2	2	3	4	5	6
3	2	3	4	5	6
4	2	3	4	5	6

Math

Write latex math equation like this

$$
F = G \frac{m_1 \times m_2}{R^2}
$$

$$F=G\frac{m_1\times m_2}{R^2}$$

Multiple columns

• Pandoc Extension: fenced_divs
• Builtin CSS class: container and col

Two-column Example

::: {.container} :::: {.col} It is two columns!

This is column 1 :::: :::: {.col} This is column 2

::: {.container}
:::: {.col}
Column 1
::::
:::: {.col}
Column 2
::::
:::

:::: :::

You can add as many columns as possible.

Multiple-column Vertical Alignment (Top)

::: {.container style="align-items: flex-start;"} :::: {.col}

col1

• Default is center alignment
• This is top alignment :::: :::: {.col}

col2

Top alignment code:

::: {.container style="align-items: flex-start;"}
:::: {.col}
col1
::::
:::: {.col}
col2
::::
:::

:::: :::

Multiple-column Vertical Alignment (Bottom)

::: {.container style="align-items: flex-end;"} :::: {.col}

• Default is center alignment
• This is bottom alignment

col1

:::: :::: {.col} Top alignment code:

::: {.container style="align-items: flex-end;"}
:::: {.col}
col1
::::
:::: {.col}
col2

Pandoc Options

Because markdown_revealjs is just

[a shell wrapper of pandoc]{style="font-size:1.5em;"}.

::: {.fragment} You can [override]{style="font-size:1.5em;"} them! :::

::: {.fragment style="font-size: 0.5em;"} See pandoc available options by pandoc -h :::

Metadata in .md file (lower priority)

Override in md file metadata, like

pandoc-opts: "<PANDOC OPTIONS>"

Example:

---
title: Markdown RevealJS
author: xieby1
date: 2022.06.10
...
pandoc-opts: "--toc=false"
---

CLI Options (higher priority)

Override by appending reveal.sh command, like

reveal.sh <MD File> <PANDOC OPTIONS>

Example:

reveal.sh README.md --toc=false

Slide Number End

Slides after the specific slides

can be excluded from the total slide number.

---

Think about a situation where,

in your PhD defense,

there are several backup slides at the end.

You do not want them counted to the total slide number.

.slide-count-end

Add .slide-count-end to the heading of the slide,

# Heading {.slide-count-end}

Example

In this README, .slide-count-end is added to slide [QnA].

Therefore, the slides after [QnA], like [Backup Slides]

are not counted to total slide number

TOC (resident)

See,

some key TOC entries are resident at the top of the slides?

Two Types of Attributes {data-auto-animate=1}

• Top slide without subsequent vertical slides
  • data-name="<TOC_Entry_Name>"
• Top slide with subsequent vertical slides
  • data-stack-name="<TOC_Entry_Name>"
• Example:

::: {.container} :::: {.col}

...
# H1 {data-name="h1"}

# H2 {data-stack-name="h2"}

## H2_1
...

:::: :::: {.col} :::: :::

Two Types of Attributes: details {data-auto-animate=1}

Hide Resident TOC {data-sminvisible=true}

Want to hide resident TOC in specific slides?

Add data-sminvisible=true to the slide heading, like

## Hide Resident TOC {data-sminvisible=true}

...

More Example

My 国科大计算所答辩 theme use resident TOC

<iframe src="./themes/ucas_ict_thesis.html" style="width:800px; height: 450px;"></iframe>

Want to know more?

Resident TOC is implemented based on revealjs plugin:

martinomagnifico/reveal.js-simplemenu.

TOC (full)

TOC Depth

Default TOC depth is 2.

You can override it in yml front matter, like

toc-depth: 1

TOC Columns

The number of TOC columns is controlled by yml front matter:

• toc-width for TOC width
• toc-column-width for TOC's column width
• toc-margin for TOC's margin

Therefore, by adjusting these two variable,

you can control how many TOC columns you have.

Default Values (3-column TOC)

• Remember the default slide width is 1200px.
• The default toc-column-width is 290px
• The default toc-margin is 0 0 0 0
• Thus a 3-column toc is presented.

1-column TOC

Here is an example of 1-column TOC

toc-width: 1200px
toc-column-width: unset
toc-margin: 0 400px

From this slide on,

the total slide number ends counting.
