The <figcaption> element is used to provide a caption to an image.
It is an optional tag and can appear before or after the content within the <figure> tag.
Only one <figcaption> element can be nested within a <figure> tag although the <figure> element itself may contain multiple other elements like <img> or <code>.
The <figcaption> element is used with <figure> element and it can be placed as the first or last child of the <figure> element.
