- @ChrisLaarman, No, I actually need it to be with an image. – Jessy Jordan Commented Jul 19, 2013 at 12:33

Reset to default 3Here is a way in Pure JavaScript. I had fun with CSS styling.
Live Demo(with text)
Live Demo (with images)
Image animation
HTML
<div>
<img id="black" src="http://www.ratemotorcycle./image1/5/53/kawasaki-ninja-zx10r-2013.jpg" />
<img id="red" src="http://imageshack.us/a/img39/3517/13kawasakizx10r1.jpg" />
</div>
CSS
#black {
/* Added the position and the z-index to ensure images overlay correctly */
position:absolute;
z-index:2;
/* styling fun */
color:black;
font-weight:bold;
font-size:2em;
/* default width */
width:768px;
}
#red {
/* Position and z-index let us overlay the #black and #red elements*/
position:absolute;
z-index:10;
/* This is to put the element directly over the #black element
(pensating the margin/padding of the #black element */
left:8px;
/* We make the initial width 0px and hide the overflow. */
width:0px;
overflow:hidden;
/* Fun styling */
font-weight:bold;
font-size:2em;
color:red;
}
JavaScript
var red = document.getElementById('red');
red.style.width = "0px";
/* set the height so the image does not "scale" */
red.style.height = "1024px";
var animation = setInterval(function () {
if (parseInt(red.style.width, 10) == 768) clearInterval(animation);
red.style.width = parseInt(red.style.width, 10) + 2 + "px";
}, 10);
Text animation
HTML
<div>
<span id="black">LOGO</span>
<span id="red">LOGO</span>
</div>
CSS
#black{
/* Fun styling */
color:black;
font-weight:bold;
font-size:2em;
}
#red {
/* Position and z-index lets us overlay the #black and #red elements*/
position:absolute;
z-index:10;
/* This is to put the element directly over the #black element
(pensating the margin/padding of the #black element */
left:8px;
/* We make the initial width 0px and hide the overflow. */
width:0px;
overflow:hidden;
/* Fun styling */
font-weight:bold;
font-size:2em;
color:red;
}
JavaScript
/* On window load (when the page is loaded) */
window.onload = function(){
/* We select our #red element */
var red = document.getElementById('red');
/* Set the width of #red to 0px */
red.style.width = "0px";
/* Create an action that will execute every 50ms */
var animation = setInterval(function(){
/* If the element is at the desired width, we clear the animation loop */
if(red.style.width == "91px")
clearInterval(animation);
/* Otherwise, we set the width+=1, ensuring to get the numeric value of it only */
red.style.width = parseInt(red.style.width,10)+1 +"px";
},50);
};
jQuery alternative
$('#red').css('width','0px');
$('#red').animate({'width':'91px'},4500);
JavaScript vs jQuery
JSPerf results
After an unofficial test battery, the jQuery animation for this purpose would be ran 85% slower than its pure JavaScript counterpart. This is a huge performance difference.
I put 2 divs over eachother with the same text, and animate 1 of them on click.
HTML
<div class="red">Text</div>
<div class="black">Text</div>
CSS
div {
position: absolute;
top: 0px;
left: 0px;
font-size: 48px;
font-family: arial;
font-weight: bold;
width: 150px;
overflow: hidden;
cursor: pointer;
}
div.red { color: red;}
Javascript
$(document).ready(function() {
$("div.black").animate({
'width': 0
}, 2000);
});
http://jsfiddle/d8LAn/3/
One way to do so would be to position 2 images one that is black and one that is red(on top) set the width of the red one to 0 and using jquery like so :
$('#redone').animate({
width: 'widthofyourelement'
}, 600)
This would give it the effect of "filling", if you wish to fill it differently i suggest checking out rhaphael.js and reading up on SVG,
Css only solution
You can do it this way with plain javascript:
function animate() {
var logo = document.getElementById('logo');
logo.style.color = 'blue';
logo.style.backgroundColor = '#ff8';
// http://stackoverflow./questions/5598743/finding-elements-position-relative-to-the-document
var elem = logo;
var offset = { top: 0, left: 0 };
do {
if (!isNaN(elem.offsetLeft)) {
offset.top += elem.offsetTop;
offset.left += elem.offsetLeft;
}
} while (null !== (elem = elem.offsetParent));
var c = logo.cloneNode(true);
c.id = '';
c.style.position = 'absolute';
c.style.top = offset.top + 'px';
c.style.left = offset.left + 'px';
c.style.color = 'red';
c.style.backgroundColor = '#8ff';
c.style.width = 0;
c.style.height = logo.clientHeight + 'px';
document.body.appendChild(c);
//logo.parentNode.insertBefore(c, logo.nextSibling); //(alternative)
var maxw = logo.clientWidth,
currw = 0;
var duration = 1000; //miliseconds
var iv = setInterval(function () {
currw += 1;
if (currw > maxw) {
clearInterval(iv);
}
c.style.width = currw + 'px';
}, (duration/maxw));
}

Only With CSS : IN HTML :-
<h1>Online<a><span>Online</span></a></h1>
And IN CSS : -
h1 {
position: absolute;
top: 0;
left: 0;
height: 100px;
line-height:100px;
width: 280px;
text-align: center;
font-size:70px;
color:#fff;
background:rgba(171,169,170,0.8);
padding:0px;
margin:0px;
cursor:pointer;
}
h1 a {
position: absolute;
top: 0;
left: 0;
height: 0px;
width: 0px;
text-align: center;
font-size: 70px;
color:#fff;
overflow:hidden;
padding: 0px;
margin: 0px;
-webkit-transition: all 400ms cubic-bezier(0.785, 0.135, 0.15, 0.86);
}
h1:hover a{
height: 100px;
width: 280px;
-webkit-transition: all 400ms cubic-bezier(0.785, 0.135, 0.15, 0.86);
}
h1 a span { position: absolute;
top: 0;
left: 0;
font-size: 70px; height: 100px;
width: 280px;
color:rgba(0, 148, 255, 0.84);
cursor:pointer;
}
