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