WCAG: 2.2.2: <blink> elements are deprecated and must not be used
This rule requires that no
blinkelements are present. Flashing text can be difficult to read and blinking objects can be difficult to activate. The associated automated check finds the presence of all
blinkelements so that they can be removed.
As the name suggests,
blinktags cause content to flash. Though you may like the effect, blinking text can be difficult to read, and blinking objects (links, buttons, etc.) can be difficult to activate, especially for users with imprecise or limited dexterity.
It can be very difficult for people with visual and cognitive disabilities to see and understand text that blinks. Blinking text be distracting, especially for users with cognitive disabilities. It can also be difficult for some individuals to comprehend. For these reasons, the
blinkelement should never be used.
