summary

The HTML <summary> element is used as a summary, caption, or legend for the content of a <details> element. This attribute defines an alternative text that summarizes the content of the table. Typically, it allows visually impaired people who are browsing the web with a Braille screen, to acquire information about the table. If the information added by this attribute is also useful to people who are not visually impaired, consider using the <caption> instead. The summary attribute is not mandatory and may be omitted when a <caption> element fulfills its role.

Usage Note: Do not use this attribute, as it has been deprecated. Instead, choose one of these methods to add a description of a table:

• Use prose around the table (this method is less semantic).
• Add a description in the table's <caption> element.
• Add a description in a <details> element, inside the table's <caption> element.
• Include the <table> element in a <figure> element and add the description in prose next to it.
• Include the <table> element in a <figure> element and add the description in prose inside a <figcaption> element.
• Adjust the table so that a description is not needed (e.g. use <th> and <thead> elements).
