Pre-loaders are a common sight in modern web design. As users we expect the web to be fast and fluid - we don’t like waiting for things. Pre-loaders offer visual feedback in the event of content being loaded, thereby managing expectations and reducing the chance of a user abandoning your website. CSS3 Essentials for Creating Pre-loaders Before we dive into building our collection of CSS3 pre-loaders, first I’ll be discussing some of the attributes of CSS3 which are essential for creating these type of pre-loaders. Pseudo Elements :before :after Pseudo elements are really useful in helping creating CSS3 pre-loaders. Pseudo elements essentially create a fake element before or after the HTML element in question. “Pseudo is derived from the Greek word pseud?s which means false.” This is similar to creating an extra element that doesn't really exist however pseudo elements can be styled using CSS. These pseudo elements aren't a necessity for creating CSS3 pre-loaders but they do come in handy and allow us to use minimal markup. Pseudo elements can be styled exactly the same way as you would any other HTML element the only difference being that you must specify a content property.
