How do I animate a glowing effect on text?

You can use .animate to cycle to a chosen colour to create a "highlight" effect which is presumably what "glowing" means.

$(".confirm_selection").hover(function() {
    $(this).animate({
        color: "red"
    }, 2000);
}, function() {
    $(this).animate({
        color: "black"
    }, 2000);
});

You can try it here.

NOTE: Colour animation requires the use of either the colour animation plugin, or jQuery UI (which I assume you are already using as it has been included in your fiddle).


Try this code:

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function ()
{
    var glow = $('h1');
    setInterval(function()
    {
        glow.toggleClass('glow');
    }, 1000);
});
</script>
<style type="text/css">
    h1 {
        -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;
        width: 725px;
    }
    h1:hover,
    h1.glow
    {
        text-shadow: 0 0 10px Green;
    }
</style>
</head>

<body>
    <h1>This text has Glow Animation Effect</h1>
    <div class="buttons">
        <input type="text" name="txt"> <input type="button" class="btnAdd" value="Add"><br>
    </div>
    <h3>J Query</h3>
</body>

</html>

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.

And finally, here's the fiddle: http://jsfiddle.net/dH6LS/

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>

Here's the fiddle: http://jsfiddle.net/dH6LS/689/

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


You can do this with pure CSS3 transitions:

div.transition{
    text-decoration: none;  
    color: blue;  
    text-shadow: none;  
    -webkit-transition: 500ms linear 0s;  
    -moz-transition: 500ms linear 0s;  
    -o-transition: 500ms linear 0s;  
    transition: 500ms linear 0s;  
    outline: 0 none; 
    background-color:#000; 
    font-size:2em;
    width:300px;     
    height:100px; 
    padding:1em;
}

div.transition:hover {
    color: #fff;  
    text-shadow: -1px 1px 8px #ffc, 1px -1px 8px #fff; 
}

Note: Glowing text works best on a dark background.
