How do you make text color text background and text blink?

JavaScript

Using CSS to achieve blinking text is highly discouraged; It has bad browser support and standardization. Some browsers may display it and others won't; Some won't display it at all!

You would have better browser support if you used JavaScript, but if you are still pushing to use CSS, the official way to create blinking text would be to use the text-decoration property with a blink value.

Example 1body

{text-decoration: blink}

The above CSS will make any text in blink.

Example 2.blink

{text-decoration: blink}

The above CSS will make any text in blink.
