				<h2>About Hover.css</h2>

				<p>All Hover.css effects make use of a single element (with the help of some pseudo-elements where necessary), are self contained so you can easily copy and paste them, and come in CSS and SASS flavours.</p>

				<p>For best results, hover effects use a couple of "hacks" (undesirable but usually necessary lines of code). For more information on these hacks and whether you need them, please read the FAQ.</p>

				<p>Many effects use CSS3 features such as transitions, transforms and animations. Old browsers that don't support these features may need some extra attention to be certain a fallback hover effect is still in place.</p>
