Introduction

Thanks to animations, websites and web applications became more interactive and vivid. The times when “website” meant “static content” have gone to past. Menu animations, slideshows, interactive charts are now an integral part of most applications. Before the introduction of the third version of CSS we had to use external libraries like jQuery or script.aculo.us for animations. Now we have two powerful features which are transitions and animations with keyframes. We’re going to focus on the first one in this article.
