The HTML figcaption Tag is used to describe an image in a figure tag. It is a child object of the figcaption figure tag and is used in itself.
<figure>
<img src="img/plane.jpg" alt="A304" style="width:100%">
<figcaption>Air Bus A304</figcaption>
</figure>
Make sure to use the figcaption figure tag inside.
