Designing Next Generation Web Projects with CSS3

Overview of this book

CSS3 unveils new possibilities for frontend web developers: things that would require JavaScript, such as animation and form validation, or even third party plugins, such as 3D transformations, are now accessible using this technology."Designing Next Generation Web Projects with CSS3" contains ten web projects fully developed using cutting edge CSS3 techniques. It also covers time saving implementation tips and tricks as well as fallback, polyfills, and graceful degradation approaches.This book draws a path through CSS3; it starts with projects using well supported features across web browsers and then it moves to more sophisticated techniques such as multi polyfill implementation and creating a zooming user interface with SVG and CSS. React to HTML5 form validation, target CSS rules to specific devices, trigger animations and behavior in response to user interaction, gain confidence with helpful tools like SASS, learn how to deal with old browsers and more."Designing Next Generation Web Projects with CSS3" is a helpful collection of techniques and good practices designed to help the implementation of CSS3 properties and features.

Animating the gauge


We can now animate the arrow using CSS transitions. Basically, we have to tell the browser that the transform property needs to be animated; the necessary SASS code is a bit longer than expected because Compass is not yet able to prefix the transition property and its value (https://github.com/chriseppstein/compass/issues/289), so we have to do it manually:

  -webkit-transition: -webkit-transform 0.5s;
  -moz-transition: -moz-transform 0.5s;
  -ms-transition: -ms-transform 0.5s;
  -o-transition: -o-transform 0.5s;
  transition: transform 0.5s;

After we have placed these CSS instructions inside the div[data-arrow] selector, we'll notice that if we change the data-percentage property, for example, by using Chrome and its development console, the arrow responds with a smooth animation.
