The figcaption tag (<figcaption>) defines a caption within a figure element. The HTML5 figcaption element must be used immediate after <figure> tag or just before </figure> tag, that means the figcaption element must be either first or last child element of its parent figure element. Only one figcaption element can be used within a figure element of HTML5 document.

Important point need to be remembered:

HTML5 figcaption element is supported by latest versions of all web browsers. Internet Explorer 8 or earlier versions of Internet Explorer do not support figcaption element.

There are some HTML5 figcaption element examples given below:
