I love icon fonts such as Font Awesome, they're actually awesome.
The use of icons is perfect for retina display devices, you can style them, animate them, transform them...
Today I want to show you how to easily create a spinner out of this icon fonts.
We'll use two concepts: @keyframes and animation.
Keyframes
We'll specify what should our animation do. In our case we can to transform (rotate) the element from 0 to 360deg
@keyframes rotation {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
Animation
We'll have two different setups here. First of all we'll use the linear attribute which will create a continuous motion.
.spinner {
animation: rotation 2s infinite linear;
}
For the other icon we want the animation to run in 8 steps. Why 8 steps? The icon we've chosen has 8 mini circles. We'll simulate a different kind of spinning. Don't worry, you'll get once you see the Demo.
.spinner {
animation: rotation 2s infinite steps(8);
}
Please notice this code is prefix free, you should add them according to your needs (-moz, -webkit, -o...). Check out the Demo source to see the prefixed attributes.
The HTML
It's just this easy:
