Summarizing Your Topic Using the Summary Markup Element in HTML5 Web Pages

By Vipul Patel


One of the new markup elements introduced in HTML5 is the summary markup element.

As the name suggests, the summary markup element is an interactive markup element used to represent summary context of your web page.


The HTML5 specification says…

The HTML5 specification for summary markup element specifies that the element can be used to represent a summary, caption or legend.

It also mandates that the summary markup element must have both a starting and an ending tag.

The summary markup element can also be inside a details markup element. When inside a details markup element, the summary element is visible irrespective of whether the open attribute of the details markup element is specified or not.



Let us write a simple HTML5 web page that uses a summary markup element.


<!DOCTYPE html>


<meta charset="utf-8">

<title>Summary sample</title>



        <h1>Summary markup element sample</h1>

        <p>Demo showing summary markup element</p>


    <summary>Summary element outside details markup element.</summary>

    <details open>

        <summary>Another Summary markup element inside details markup element</summary>



        <p>HTML Goodies</p>





The web page is rendered in Google Chrome as under.
