# Failure of Success Criterion 2.2.2 due to using the blink element

ID: F47

Technology: failures

Type: Failure

## When to Use

HTML

## Description

The blink element, while not part of the official HTML specification, is supported by many user agents. It causes any text inside the element to blink at a predetermined rate. This cannot be interrupted by the user, nor can it be disabled as a preference. The blinking continues as long as the page is displayed. Therefore, content that uses blink fails the Success Criterion because blinking can continue for more than three seconds.

## Examples

A product list page uses the blink element to draw attention to sale prices. This fails the Success Criterion because users cannot control the blink.

    <p>My Great Product <blink>Sale! $44,995!</blink></p>

## Tests

### Procedure

1. Examine code for the presence of the blink element.

### Expected Results

- If #1 is true, the content fails the Success Criterion.
