wtf is css-loaders?

CSS Loaders is a collection of animated loading spinners built entirely with CSS. Each spinner is made from a single HTML element, a div with a class of "loader", with no additional markup beyond optional CSS pseudo-elements. The text content "Loading..." is included for screen readers and older browsers that may not support CSS animations. The project was created with a deliberate constraint: every spinner must use exactly one HTML element. The idea behind this limit is that a loading indicator is a small, simple thing that should not require complex markup. Because all sizing uses the em unit relative to a base font size, you can resize any spinner by changing just the font-size property on it. The spinners work across a broad range of browsers including Internet Explorer 10 and later, Chrome 4 and later, Firefox 16 and later, Opera 15 and later, and Safari 4 and later. A live demo is linked from the project README so you can preview each animation style before deciding which one to use in your project.
