reveal.js comes with a speaker notes plugin which can be used to present per-slide notes in a separate browser window. The notes window also gives you a preview of the next upcoming slide so it may be helpful even if you haven't written any notes. Press the »S« key on your keyboard to open the notes window.
A speaker timer starts as soon as the speaker view is opened. You can reset the timer by clicking on it.
Notes are defined by appending an
<aside> element to a slide as seen below. You can add the
data-markdown attribute to the aside element if you prefer writing notes using Markdown.
Alternatively you can add your notes in a
data-notes attribute on the slide. Like
<section data-notes="Something important"></section>.
When used locally, this feature requires that reveal.js runs from a local web server.
Shhh, these are your private notes 📝
If you're using the Markdown plugin, you can add notes with the help of a special delimiter:
<section data-markdown="example.md" data-separator="^\n\n\n"
Here is some content...
This will only display in the notes window.
Adding the Speaker Notes Plugin
The plugin is already bundled with reveal.js. To enable the speaker notes plugin, add the plugin source to the
index.html and add the plugin to the initialization of reveal.js.
plugins: [ RevealNotes ]
Share and Print Speaker Notes
Notes are only visible to the speaker inside of the speaker view. If you wish to share your notes with others you can initialize reveal.js with the
showNotes configuration value set to
true. Notes will appear along the bottom of the presentations.
showNotes is enabled notes are also included when you export to PDF. By default, notes are printed in a box on top of the slide. If you'd rather print them on a separate page, after the slide, set
Speaker Notes Clock and Timers
The speaker notes window will also show:
- Time elapsed since the beginning of the presentation. If you hover the mouse above this section, a timer reset button will appear.
- Current wall-clock time
- (Optionally) a pacing timer which indicates whether the current pace of the presentation is on track for the right timing (shown in green), and if not, whether the presenter should speed up (shown in red) or has the luxury of slowing down (blue).
The pacing timer can be enabled by configuring the
defaultTiming parameter in the
Reveal configuration block, which specifies the number of seconds per slide. 120 can be a reasonable rule of thumb. Alternatively, you can enable the timer by setting
totalTime, which sets the total length of your presentation (also in seconds). If both values are specified,
totalTime wins and
defaultTiming is ignored. Regardless of the baseline timing method, timings can also be given per slide
<section> by setting the
data-timing attribute (again, in seconds).
Server Side Speaker Notes
In some cases it can be desirable to run notes on a separate device from the one you're presenting on. The Node.js-based notes plugin lets you do this using the same note definitions as its client side counterpart. See https://github.com/reveal/notes-server.
