Attributes

This element includes the global attributes.

cite

This attribute defines the URI of a resource that explains the change, such as a link to meeting minutes or a ticket in a troubleshooting system.

datetime

This attribute indicates the time and date of the change and must be a valid date with an optional time string. If the value cannot be parsed as a date with an optional time string, the element does not have an associated time stamp. For the format of the string without a time, see Format of a valid date string. The format of the string if it includes both date and time is covered in Format of a valid local date and time string.

Examples

<ins>This text has been inserted</ins>

Accessibility concerns

The presence of the <ins> element is not announced by most screen reading technology in its default configuration. It can be made to be announced by using the CSS content property, along with the ::before and ::after pseudo-elements.

ins::before,
ins::after {
  clip-path: inset(100%);
  clip: rect(1px, 1px, 1px, 1px);
  height: 1px;
  overflow: hidden;
  position: absolute;
  white-space: nowrap;
  width: 1px;
}

ins::before {
  content: " [insertion start] ";
}

ins::after {
  content: " [insertion end] ";
}

Some people who use screen readers deliberately disable announcing content that creates extra verbosity. Because of this, it is important to not abuse this technique and only apply it in situations where not knowing content has been inserted would adversely affect understanding.
