HTML pages in slides¶

Run a Plotly chart, a Brax viewer, or any HTML page inside a slide, and keep the deck fast.

Departure speed peaks at 22 N m.

![Plot, seed 2](assets/plot.html?seed=2)

mkdeck keeps the query, ?seed=2, in the page address, but it leaves the query off the file name. So it copies the file assets/plot.html.

How pages load¶

mkdeck limits how many pages run at once by applying three rules:

1. The current slide loads its page at once.
2. The two neighboring slides load their pages lazily, which means the browser decides when.
3. mkdeck removes the iframes of every other slide.

Removing an iframe frees its WebGL context. As a result, a deck with dozens of slides and many megabytes of WebGL pages still answers a key press at once.

Reload a stalled page¶

Press R during a talk to reload the figures on the current slide, for example when a viewer stalls. Your own script can call window.mkdeck.reloadEmbeds() to do the same. See Custom JavaScript.

Keep pages small¶

mkdeck warns you at build time when a page is larger than 2 MB, and it gives the warning once for each file. A deck full of large pages opens slowly.
