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:

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

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>
