Link targets
Accessibility guidelines advise that:
Opening new tabs/windows should be minimised, unless there is a good reason (such as needing to view instructions for a form separately, or to display terms and conditions relating to a form).
Vision impaired users and neuro-diverse users need to be warned that a link will open a new tab/window.
Our approach
For all links, ensure that it is possible for users to control when a link opens in new tab/window by making sure the browser’s native “Open in new tab” and “Open in new window” options are always available.
For links which open in an new window.
Append a standard icon to the end of the link
import OpenInNewIcon from '@mui/icons-material/OpenInNew';
Hide the icon from screen readers
aria-hidden="true"
Ensure the words “opens in a new window” are voiced by screen readers
append the screen reader warning automatically at the end of the link following the icon.
