### Why is this important?
The text inside a `blink` element can blink at a predetermined rate as there is no way to interrupt or disable blinking.
Although blinking draws attention to the content, it can be a problem for some users if it persists and may make it difficult or impossible to interact with the rest of the page.
The use of the `blink` element has been deprecated.

<div id="locSnippet"></div>
### What to do
* If there is a need to include blinking content, use a technology that stops blinking in 5 seconds or less
* **Or**, provide an option to turn off blinking
* **Or**, provide a link to an alternative page without the blinking content
