Preface

This book is intended for designers who have a basic understanding of HTML and CSS,

but want to advance their skill set by learning basic JavaScript. It's not necessary that you

understand JavaScript well. Even if you've never aempted to write JavaScript before, this

book will guide you through the process of seng up basic JavaScript and accomplishing

common tasks such as collapsing content, drop-down menus, and slideshows; all thanks to

the jQuery library.

What this book covers

Chapter 1, Designer, Meet jQuery, is an introducon to the jQuery library and JavaScript.

You'll learn about jQuery's rise to fame, why it's so great for designers, and how it can help

you create some fancy special eects without having to learn a lot of code. This chapter

also includes a gentle and small introducon to JavaScript, progressive enhancement,

and graceful degradaon, and guides you through wring your rst JavaScript code.

Chapter 2, Enhancing Links, walks you through some basic enhancements to links. You'll

learn how to use jQuery to turn a list of links into a tabbed interface. Then, we'll take our

rst look at jQuery plugins where you'll learn to add custom toolps to your links using the

jQuery PowerTip plugin.

Chapter 3, Making a Beer FAQ Page, will introduce you to collapsing and showing content,

as well as creang simple animaons and traversing an HTML document to move from one

element to another. In this chapter, we'll set up a basic FAQ list, then work to progressively

enhance it to make it easier for our site visitors to use.

Chapter 4, Building an Interacve Navigaon Menu, guides you through seng up fully

funconing and visually stunning drop-down and y-out menus. We'll walk through the

complex CSS required to get these types of menus working, use the Supersh plugin to

ll in features missing from pure CSS soluons, and then take a look at customizing the

appearance of the menus.

Chapter 5, Showing Content in Lightboxes, will walk you through showing photos and

slideshows in a lightbox using the Colorbox jQuery plugin. Once we get the basics down,

we'll also take a look at using the Colorbox plugin to create a fancy login, play a collecon

of videos, and even set up a single-page website gallery.

Chapter 6, Creang Slideshows and Sliders, walks you through seng up a simple crossfade

slideshow without a plugin. Then, we'll take a look at the Basic Slider plugin to create a

simple slideshow with controls. Finally, we'll take a look at the Cycle2 plugin, a exible and

customizable opon that can be used to create sliders, slideshows, and carousels.

Chapter 7, Working with Responsive Designs, will dive deep into jQuery techniques for

responsive designs. This includes ng videos to the viewport, turning a drop-down

menu into a responsive menu, and building a led layout for displaying image galleries.

Chapter 8, Geng the Most from Images, walks you through a few techniques to work with

images in a more eecve way. We'll take a look at lazy-loading images so that images are

only loaded if our site visitor scrolls to them. We'll add an image zoom capability and nally,

we'll take a look at creang fullscreen background images and slideshows for our pages.

Chapter 9, Improving Typography, shows you techniques to deal with typography eecvely

in responsive designs. We'll take a look at the FitText plugin to t headlines to the width of

the browser window, the SlabText plugin to create mulline headlines, the Leering.js plugin

to ne-tune kerning and to apply special eects, and nally, the ArcText plugin to set a text

on a curve.

Chapter 10, Displaying Data Beaufully, takes a look at the important task of displaying data

in an easy-to-understand way for your site visitors. First of all, we'll take a look at turning an

ordinary HTML table into an interacve data grid with the DataTables plugin. Then, we'll look

at turning HTML tables into charts and graphs that communicate our data clearly to our site

visitors in an accessible and progressively enhanced way.

Chapter 11, Reacng to Scrolling, dives into the fun task of scrolling animaons and parallax

eects. We'll use the Scrollorama plugin to create a parallax eect, trigger animaons on

scroll, and acvate a navigaon bar that reacts to us scrolling down the page.

Chapter 12, Improving Forms, takes a look at how forms can be improved. This chapter

walks you through seng up an HTML form properly using some of the latest HTML5 form

elements. Then, we enhance the form by placing the cursor in the rst eld and validang

the site visitor's form entries. Finally, we take a look at the FancyForm jQuery plugin, which

allows us to style even the most stubborn and challenging form elements to achieve a

consistent look for our forms across browsers.

What you need for this book

You'll need a text editor to create HTML, CSS, and JavaScript les. Some great free opons

available are TextWrangler for Mac or Notepad++ for Windows. There are many other

opons available, and you are free to use your favorite text editor for any of the examples

in this book. My personal favorite is Sublime Text, which is easy to work with and has a very

nice feature set. If you haven't tried it before, I encourage you to download an evaluaon

copy for free to give it a try.

You'll also need a browser. My personal favorite is Google Chrome, which includes some

really helpful built-in debugging tools for both CSS and JavaScript. Again, you are free to

use your favorite browser for the examples in the book.

If you want to create images for your own designs, then Adobe Photoshop and Adobe

Illustrator will be helpful, though they are not strictly necessary. All images needed to

set up the examples used in this book are included in the sample code.

jQuery and jQuery plugins are being updated all the me. As new browsers are released

with new support and capabilies, and as JavaScript, HTML, and CSS are further developed,

new versions of jQuery and plugins are released to keep pace with the change. On one hand,

this is a great news—jQuery and accompanying plugins get faster and more powerful all

the me. On the other hand, it can be tough to keep up with all the changes. All versions

of the plugins referenced were current at the me of wring the book, but you might nd

some dierences when you work through the exercises. Plugin developers are usually very

good at documenng the changes and updates, so don't be afraid to read through the

documentaon so you can understand what's changed and what adjustments you might

need to make.

Who this book is for

This book is for designers who know the basics of HTML and CSS, but want to extend their

knowledge by learning how to use JavaScript and jQuery.
