Figure and caption (figure-figcaption)
Ensure captioned images and diagrams are marked up with a <figure> element containing a <figcaption>.
Figcaption not first or last child:
In this example the <figcaption> is placed between other children of <figure>. Per the HTML content model, if a <figcaption> is present, it must be the first or the last child of its parent <figure>.
