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.

Implementing Flexible Box Layout


CSS2.1 defined four layout modes: block, inline, tabular, and positioned. CSS3 has added some new layout modes, and one of them is Flexible Box Layout. This new mode is activated by a new value we can give to the display statement, and can be configured through a whole new set of properties.

The basic idea behind this new layout mode is that within a container element (for example, our section element) we can specify the direction we want our inner elements to be displayed in. So if we say horizontal then the elements will flow from left to right, and if we say vertical they'll be positioned one below the other, top to bottom.

Then we can decide the size of each of the elements either by using fixed dimensions or by defining a grow factor.

Note

When a new space is available within the container, the elements increase their width proportionally to their grow factors.

Enough talk! Let's create a small demo to test this out:

<!doctype html>
<html>
