CSS3 Loading Circle

I have a CSS3 Circle Loader that has 3 circles. I am having problems Each circle (starting from the first) should fade out after a few seconds possibly using CSS Animations. Any help is appreciated.

As others have said, using animations and timing is essencial here.
In fact, each circle is used the same animation,
but you must apply a different delay to each circle.

See below (I'm also using nth-child instead of first-child):

.circle span {
    /** The same animation to each circle **/
    -webkit-animation: circleFade 3s linear infinite;
}

/** Different animation delays **/
.circle span:nth-child(1) { -webkit-animation-delay: 1s; }
.circle span:nth-child(2) { -webkit-animation-delay: 2s; }
.circle span:nth-child(3) { -webkit-animation-delay: 3s; }

/** Animation **/
@-webkit-keyframes circleFade {
     0% { background: #ddd; }
    25% { background: #999; }
    35% { background: #999; }
    60% { background: #ddd; }
}​

Use of keyframes will do it: http://jsfiddle.net/Nux3z/

Couple of details:

1) Use of :nth-child, or :first-child, etc to target your elements
2) Timing of animations: I'm using 1.7, 2.7, rather than 0.7s, 1.4s because I'm allowing for the 1s of fade to finish NOT simply doubling/tripling the time each element takes to animate.
3) Not a solution for IE

I'd go a slightly different route. Only made for webkit but you can alter as needed: http://jsfiddle.net/8kQ2u/17/

@-webkit-keyframes fades {
    0%, 100% { 
       opacity: 1;
    }
    50% {
       opacity: 0;
    }
}

.circle span  {
  display: inline-block;
  width: 15px;
  height: 15px;
  margin: 9.975em auto;
  background: #dbdbdb;
  -webkit-border-radius: 50px;
  -moz-border-radius: 50px;
  -ms-border-radius: 50px;
  -o-border-radius: 50px;
  border-radius: 50px;
  -webkit-animation-duration: 1.5s;
  -webkit-animation-name: fades;
  -webkit-animation-iteration-count: infinite;
}

.circle span:nth-child(2) {
    -webkit-animation-delay: 0.2s;
}

.circle span:nth-child(3) {
    -webkit-animation-delay: 0.4s;
}
​

:nth-child here is fine since I'm pretty sure it has full support in browsers that support @keyframes. You could use the sibling selector if you prefered (+).
