This pertains to images in Wordpress for optimizing. There is a element figcaptionyou can add for seo purposes. I am already aware of using the media library that allows you the ability to add ALT info, CAPTION etc. that way....but would appreciate learning more about figcaption within a figure. I.e.:

<figure>
<img src="pictures/this-photograph.jpg" alt="Nice bit of text which describes what's
in the picture for the benefit of robots and the visually impared">
<figcaption>Hilarious caption to accompany the cartoon</figcaption>
</figure>


Is there a way to achieve this in CSS?
