To create a blinking text, use the JavaScript blink() method. This method causes a string to blink as if it were in a BLINK tag.
Note − HTML <blink> tag deprecated and is not expected to work in every browser.
Example
You can try to run the following code to create a blinking text with the JavaScript blink() method −
<html>
<head>
<title>JavaScript String blink() Method</title>
</head>
<body>
<script>
var str = new String("Demo Text");
document.write(str.blink());
document.write("<br><br> Note: HTML <blink> tag deprecated and is not expected to work in every browser.")
</script>
</body>
</html>
