reveal.js image vs figure

reveal.js image vs figure

I'm messing around with reveal.js css, trying to get it to show images as 
large as possible, and I notice that when converting from markdown, if an 
image has a "caption", it shows up as a figure in the reveal.js html, but 
otherwise it shows up as just an image in p tags.

Specifically:

1. ![Caption](image url) turns into:

<figure>
<img data-src="/path/to/image" alt="Caption" /><figcaption>Caption
</figcaption>
</figure>


2. ![](image url) turns into:

<p>
<img data-src="/path/to/image" />
</p>

What's the logic here?

Thanks.

@JGM reminds me that this was in a recent changelog (2.0):

Require nonempty alt text for implicit_figures (#2844 
> <https://github.com/jgm/pandoc/issues/2844>). A figure with an empty 
> caption doesn’t make sense.


However you can force a figure by including a title in the image link:

![](image url "fig: test")

The img will be inside figure tabs instead of p tags and will look like 
this:

<img data-src="/path/to/image.jpg" title=" test" />

This should eliminate any potential issues with reveal.js CSS treating it 
differently.

I'm having the same issue. This solves the problem with reveal.js. But when 
producing beamer from the same source, en empty caption appears.... weird.

Not an answer, but getting reveal.js to show images as large as possible is 
a bit of a bear.  You can find a few threads on the reveal GitHub pages.
