How can I pulse the glow effect in HTML

Posted on 2015-01-28
Last Modified: 2015-01-28
Hi all,

I would like some HTML text to have a glow effect; something like this:
<!doctype html>
h1 {
    text-shadow: 0 0 3px #FF0000;
    color: white;
<h1>Text-shadow with red neon glow</h1>

Open in new window

However, I would like either the glow or text color to fade between two colors, to bring this section to the operators attention.
I need to be able to use this code in IE11, Firefox and Chrome.
Any idea how I can achieve this?
Any help would be appreciated.
Many thanks,

you can use js to add a class, and a timeout to remove the class. the fade effect can be achieved with a css transition.

Here is a fiddle. Click on the text:

That looks almost perfect!
How do I do this effect continuously without intervention from the user?

you could do it on page load.. not sure that's what you want though - it would be pretty annoying. hold on, let me modify the script.
