CSS3 Animated Gears

In today’s lesson, we have made the animated gears with CSS3. The result looks very nice. I have used CSS3 keyframes, animation and transforms (rotate) in order to achieve this result. Please pay attention – current demo works well in Firefox and Chrome / Safari (webkit).

Here are samples and downloadable package:

Ok, download the example files and lets start coding !

Step 1. HTML

As usual, we start with the HTML. Here is the html code of our result. There are easy DIV elements.

index.html

<div class="container">
    <div class="gear" id="gear1"></div>
    <div class="gear" id="gear2"></div>
    <div class="gear" id="gear3"></div>
    <div class="gear" id="gear4"></div>
    <div class="gear" id="gear5"></div>
    <div class="gear" id="gear6"></div>
    <div class="gear" id="gear7"></div>
</div>

Step 2. CSS

Here are the CSS styles of our animated gears.

css/layout.css

/* CSS3 keyframes */
@-webkit-keyframes ckw {
    0% {
        -moz-transform: rotate(0deg);
        -webkit-transform: rotate(0deg);
    }
    100% {
        -moz-transform: rotate(360deg);
        -webkit-transform: rotate(360deg);
    }
}
@-moz-keyframes ckw {
    0% {
        -moz-transform: rotate(0deg);
        -webkit-transform: rotate(0deg);
    }
    100% {
        -moz-transform: rotate(360deg);
        -webkit-transform: rotate(360deg);
    }
}
@-webkit-keyframes cckw {
    0% {
        -moz-transform: rotate(360deg);
        -webkit-transform: rotate(360deg);
    }
    100% {
        -moz-transform: rotate(0deg);
        -webkit-transform: rotate(0deg);
    }
}
@-moz-keyframes cckw {
    0% {
        -moz-transform: rotate(360deg);
        -webkit-transform: rotate(360deg);
    }
    100% {
        -moz-transform: rotate(0deg);
        -webkit-transform: rotate(0deg);
    }
}
