Overview of this book

jQuery UI is the quintessential framework for creating professional user interfaces. While jQuery core lays the foundation for interaction with the DOM and handling events, jQuery UI fills in the user interaction gap. This book will give you a huge productivity boost out of the box with jQuery UI, and help you understand the framework, inside and out."jQuery UI Cookbook" provides you with practical recipes featuring in-depth coverage of every widget in the framework, including how to address limitations that impact your everyday development activities with these widgets. You'll get a better idea of the big picture – how the framework is composed, how the widgets relate to one another, and how to build on those patterns.Be it a minor tweak on the visual design of a progress bar or a fundamental change in a widget to meet your needs, "jQuery UI Cookbook" covers scenarios both big and small. You can show reminders as tooltips, apply a variety of effects to the menu widget, and start interactions between the dialog widget and API data using deferred objects. These and many more interesting tasks are covered in this book, which can be done with smooth learning and great understanding. You will see how button widgets can fill the width of their containing element, making the layout more consistent. Tabs can be sorted and moved between widgets. You will learn how to do all these things within the context of the big picture, by finding out why the components work the way they do, making you well-versed in jQuery UI.

Controlling spacing with themes

The space between accordion sections is controlled by the CSS theme framework. In particular, the visual structure for the accordion is defined by a set of CSS rules that can be modified to control the spacing between accordion sections. We could override the accordion theme CSS to adjust for more or less spacing between sections.

How to do it...

We're going to supply an additional CSS module to our UI—one that overrides the accordion structure supplied in the theme we happen to be using. There's no need to fret, however, our change is a simple one. We're going to update the margin-top property. In a new CSS file called theme.accordion.css, let's add the following style rules:

.ui-accordion .ui-accordion-header {
    margin-top: 4px;

Now that we have the CSS, we need to include it in our HTML header. It should look something like this:

How it works...

We're copying the same CSS selector as is found in any jQuery UI theme. The particular property we've just changed alters the space between the accordion sections. Since we're overriding the default theme value, it's important to include our CSS files after the default theme file. This allows us to override the default theme instead of the default theme overriding our modifications.
