The HTML code to wrap text in HTML blink tags can be generated using JavaScript:
MyHTML = MyText.blink();Two Important Notes About the Blinking HTML and JS!
- The blink JavaScript method is not standardized and may not behave consistently in all browsers.
- The blink HTML tag does not function at all in many modern web browsers.
Using either the JavaScript blink method or using the HTML tag should be avoided.
If you would like to have elements blink, such as text or images, then you must use CSS and HTML.
Since the blink JavaScript method will produce still valid markup, a functional example that demonstrates the old method is provided here.
Working JavaScript and CSS Blinking Text Example
Although the blink HTML tag is no longer used, it is relatively easy to achieve the blinking effect using HTML and CSS.
This example below uses JavaScript in the case that you can not easily add a style to the document any other way.
A more common way to add the style would be to add a style tag to the page instead of inserting the new style tag into the document head through the DOM.

</html>Pure HTML and CSS Blinking Text Example
The most common situation would be that JavaScript is not needed to achieve the blinking effect.
This example below only uses HTML and CSS, and there is no JavaScript code used at all.

<title>JavaScript String Blink Method Example</title>
</head>
<body>
<script>
var MyText = "Demo of the JavaScipt Blink String Method";
var MyHTML = MyText.blink();
document.write(MyHTML);
</script>
</body>
</html>Which will create the following HTML:
<blink>Demo of the JavaScipt Blink String Method</blink>Using the Blink Method With An Argument
The blink method does not take an argument, but passing an argument to it does not generate an error message. This behavior is consistent with other string methods that do not expect an argument.
MyText.blink("this text passed as an argument does nothing");Using the Blink Method Without a Variable
It is worth mentioning that the blink method can be called on a string that is not stored in a variable.
The following code will work but is discouraged because it can be confusing to read.
document.write('Non-functional Blinking Text'.blink());JavaScript will determine that the text within the quotes is a string and apply the blink() method to it.
