If you want to just use CSS3, you don't even have to use any jQuery/JavaScript. Just do this in your CSS:

.confirm_selection {     -webkit-transition: text-shadow 0.2s linear;     -moz-transition: text-shadow 0.2s linear;     -ms-transition: text-shadow 0.2s linear;     -o-transition: text-shadow 0.2s linear;     transition: text-shadow 0.2s linear; } .confirm_selection:hover {     text-shadow: 0 0 10px red; /* replace with whatever color you want */ } 

Here's the fiddle: http://jsfiddle.net/zenjJ/

If you want the element to run on its own (without hovering), do this:

CSS:

.confirm_selection {     -webkit-transition: text-shadow 1s linear;     -moz-transition: text-shadow 1s linear;     -ms-transition: text-shadow 1s linear;     -o-transition: text-shadow 1s linear;     transition: text-shadow 1s linear; } .confirm_selection:hover, .confirm_selection.glow {     text-shadow: 0 0 10px red; } 

JavaScript:

var glow = $('.confirm_selection'); setInterval(function(){     glow.toggleClass('glow'); }, 1000); 

You can play around with the timing in the CSS/JavaScript to get the exact effect you're looking for.

Update Oct. 2013: being that all major browsers now support CSS animations, all you need is this:

.confirm_selection {      animation: glow .5s infinite alternate;  }    @keyframes glow {      to {          text-shadow: 0 0 10px red;      }  }    .confirm_selection {      font-family: sans-serif;      font-size: 36px;      font-weight: bold;  }

<span class="confirm_selection">  [ Confirm Selection ]  </span>

Don't forget to include all the different vendor prefixes in production.
