Features
Markdown
Create reveal.js presentation directly from markdown file,
open or create a new file in markdown and use default slide separator to see slide counter change in the status bar and title appear in the sidebar.
Since Reveal.js use marked to parse the markdown string you can use this in your document:
- GitHub flavored markdown.
- GFM tables
If you need a sample file you can get it here:
https://raw.githubusercontent.com/tokiedokie/reveal-markdown/master/sample.md
Status bar
As soon as your markdown document has at least two slides, slides counter will appear in the status bar on right.
Clicking on slide counter will launch preview on right, and you can now see the local address of express server used to host Reveal presentation.
Clicking on the address will launch presentation in the browser.
You can stop express server when you want by clicking on the red square.
Now in version 2, you can see a list of all your slides on the sidebar.
The list will show the first line of text that is found in the slide, most of the time it will be a title, but it can also be an image or something else.
Blue icon is used to show horizontal slide, orange is used for vertical ones.
Clicking on slide name will move the cursor on beginning of the slide in the editor.
If the preview is opened it will also show the selected slide on it.
Theme
reveal.js comes with a few themes built in:
- Black (default)
- White
- League
- Sky
- Beige
- Simple
- Serif
- Blood
- Night
- Moon
- Solarized
You can set it using revealjs.theme parameter in Vs code config or in the document itself using front matter.
If you want a custom theme you can do it!
Just add custom style to a CSS file in the same folder that your markdown.
example:
if your file name is my-theme.css just add this in the front matter header :
---
customTheme : "my-theme"
---
Note that you can use both theme and custom theme at the same time. Your custom theme will be loaded after to override default reveal.js theme.
Highlight Theme
You can use code block in your markdown that will be highlighted by highlight.js.
So you can configure the coloration theme by setting revealjs.highlightTheme parameter of VS Code, or set it using front matter.
---
highlightTheme : "other theme"
---
