Designing Next Generation Web Projects with CSS3

By: Sandro Paganotti

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.

Adding Polyfills


For the first time since the beginning of this book, we are using CSS3 to define the structure of our page. This means we cannot simply rely on graceful degradation to support older browsers because it would compromise the whole structure of the project. Instead, we're going to look for some JavaScript libraries that are able to emulate the behavior we have implemented. This, of course, can lead to some problems if the user's browser is missing both JavaScript support and Flexible Box Layout, but at least we can hope that the number of such users is pretty low.

There are different types of such JavaScript libraries, categorized by how much extra work is required to obtain the same result as the native implementation:

  • Generic libraries: Generic libraries don't allow the developer to obtain exactly the same result, but give him/her some tools to code an alternative implementation of the solution.

  • Shims: Shims allow the developer to mimic the native implementation perfectly...
