RESS is a new methodology in the world of web design and development. It attempts to solve the problems that accompany the Responsive Web Design (RWD) approach to web design. RESS is still in its infancy, but it is growing at an exponential rate.
RESS Essentials shows you how to make server-side applications smarter and more aware of a visitor's environment limitations (device, screen size, and browser). This allows you to create faster and more reliable websites. Through this book, you will build a solid base of knowledge on RESS-related technologies, while the step-by-step tutorials will help you to create your own RESS system.
This book is an introduction to the RESS alchemy and gives you an incentive to build your own RESS lab. It will give you a broad overview of the multiple techniques used to code responsive websites in responsible ways. Beginning with an overview of RWD, you will learn the steps involved in setting up RWD for client-side development. You will then learn how to scale images using client and server-side technology. By the end of this book, you will have learned about the implementation of RESS application patterns, browser feature detection, and various RESS architectures. This book will also teach you how to use jQuery with some RWD design patterns and how to employ REST API for RWD pages.
Chapter 1, Why Does RWD Change the Internet?, is a brief description of Responsive Web Design history, its benefits, and the controversies it caused among web developers. It also gives a brief introduction to RESS.
Chapter 2, Sample RWD Setup for Client-Side Development, describes creating a sample responsive HTML document with the help of Twitter's Bootstrap framework and Gridpak tool.
Chapter 3, Server Side Setup – Device Detection Libraries, covers using WURF (OnSite and Cloud versions) and Dave Olsen's Detector library to detect device features.
Chapter 4, Sample RESS Page, explains four complete RESS solutions to get a device's information that can be used to build an appropriate version of an HTML document within server-side application.
Chapter 5, Responsive Images Client- and Server-Side Approaches, talks about several ways to deliver resolution-dependent images, such as the script from adaptive-images.com, the <picture> element polyfill, or the RESS solution from the previous chapter.
Chapter 6, Performance, explains optimization strategies and useful tools.
Chapter 7, Extending with jQuery, starts by integrating the Twitter Bootstrap carousel component with our RESS test system. Next it covers creating the jQuery plugin from scratch to make the table responsive by converting it into an accordion component below the screen width defined with the media query.
Chapter 8, Employing a REST API for RWD, explains how to create a REST API with a Slim PHP framework and an AJAX application integrated with our RESS module, which we created before.
To run some examples from this book you need to have some kind of AMP (Apache, mySQL, PHP) environment. For those using Windows, the easiest way to go is to use the WAMP server in the default configuration. Links to the respective packages for other systems can be found at http://en.wikipedia.org/wiki/List_of_Apache–MySQL–PHP_packages.
This book is aimed primarily at web developers interested in writing applications that leverage both client-and server-side code to optimize content for various devices.
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "We can include other contexts through the use of the include directive."
A block of code is set as follows:
<picture alt="">
<source media="(min-width: 45em)"
srcset="large-1.jpg 1x, large-2.jpg 2x">
<source media="(min-width: 18em)"
srcset="med-1.jpg 1x, med-2.jpg 2x">
<source srcset="small-1.jpg 1x, small-2.jpg 2x">
<img src="small-1.jpg">
</picture>New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the JavaScript components section, do not select any checkbox."
