<summary>

Summary

The HTML summary element (<summary>) is used as a summary, caption, or legend for the content of a <details> element.

Note: If the <summary> element is omitted, the heading "details" will be used.
Note: The default style for <summary> is display:list-item per HTML standard.  If the style is being changed to display:block, the disclosure triangle will be dismissed, which is expected. See Bug 1283989 for more information.
