The hgroup element (<hgroup>) is used to group heading with associated sub-headings. More specifically it can say that HTML5 hgroup tag is used for grouping <h1> – <h6> tags. It works just like a container of two or more related heading elements.
Important point need to be remembered:
There is a HTML5 hgroup element example given below:
<article> <hgroup> <h1>Title of article goes here</h1> <h2>Sub-title of article goes here</h2> </hgroup> <p>Article content goes here...</p> </article>
