Using the data-role attribute
JQuery Mobile uses the data-role attribute to define the role of an element in the site structure web. For example, you can use the data-role="header" attribute to define an element as the page header, data-role="content" to define an element as the main content, and data-role="footer" to define an element as the footer. By using these attributes, JQuery Mobile is able to correctly style and position elements on the page.
Creating pages and transitions
JQuery Mobile makes it easy to create mobile pages using the mobile website structure described above. You can create pages using div tags with the data-role= "page" attribute. It's also possible to define transitions between pages using the data-transition attribute with a value such as "slide", "fade", "flip", etc. These transitions add visual effects when moving from one page to another.
Page navigation
Navigation between pages in a mobile website is supported by JQuery Mobile. You can create links between pages using tags with the href attribute defining the URL of the destination page. When the user clicks on a link, JQuery Mobile will load the new page using AJAX, making it possible to navigate between pages without reloading the whole page. What's more, JQuery Mobile supports back navigation, meaning the user can return to the previous page using the browser's navigation buttons.
Themes and styles
Theme customization
JQuery Mobile offers a customization framework that makes it easy to personalize the appearance of mobile websites. This framework uses CSS files to define basic styles, such as colors, fonts, margins and so on. These styles can be customized by modifying the CSS files, or by using the online customization tool provided by JQuery Mobile. This makes it possible to create mobile websites with a unique appearance tailored to your needs.
Using predefined CSS classes
JQuery Mobile also provides a set of predefined CSS classes that allow you to quickly style the elements of your mobile website. These classes can be added to HTML tags to apply specific styles and features. For example, the ui-btn class can be used to style a button. ui-listview can be used to create a list, etc. By using these predefined classes, you can speed up the development process and guarantee a consistent look and feel throughout your mobile website.

Optimized for performance
Minifying and concatenating Javascript files
To improve website performance For mobile applications, we recommend minifying and concatenating your JavaScript files. Minification involves removing unnecessary spaces, comments and characters from JavaScript files, reducing their size and making them load faster. Concatenation involves combining several JavaScript files into a single one, thereby reducing the number of HTTP requests and speeding up resource loading.
Image display optimization
Images can have a significant impact on the performance of mobile websites. We recommend optimizing images by using appropriate file formats, such as JPEG or PNG, and reducing their size to the appropriate resolution and quality. It is also possible to use delayed image loading techniques, such as lazy loading, to further improve performance. Finally, it's important to specify the size of images in HTML tags to avoid repositioning and recalculation of the layout.
Caching static resources
To reduce the loading time of static resources such as CSS files, JavaScript and images, we recommend using the browser cache. The cache allows resources to be temporarily stored locally, enabling them to be retrieved more quickly on subsequent visits to the website. You can specify how long resources should be cached using the HTTP "Cache-Control" header, or by adding "cache.manifest" tags for mobile web applications.
Using JQuery Mobile with other frameworks
Integration with Bootstrap
JQuery Mobile can be integrated with the Bootstrap framework to create responsive, user-friendly mobile websites. Bootstrap provides predefined components and styles to create attractive user interfaces, while JQuery Mobile brings mobile-specific features such as page navigation and smooth transitions. By combining these two frameworksWith this new approach, developers can benefit from the advantages of both in a single project.
Combining with AngularJS
JQuery Mobile can also be used in combination with AngularJS, a JavaScript framework popular for creating web applications. AngularJS provides advanced features for data binding, DOM manipulation and event handling, while JQuery Mobile brings mobile-specific functionality to the table. By combining these two frameworks, developers can create powerful, responsive mobile web applications.
Testing and debugging
Debugging tools available
To facilitate the process of debugging mobile websites created with JQuery Mobile, there are several tools available. Some browsers, such as Chrome and Firefox, offer integrated development tools for inspecting and debugging JavaScript code, checking page rendering and simulating different mobile devices. There are also third-party tools, such as Weinre and Adobe Edge Inspect, which offer additional functionality for debugging mobile websites.
Testing on different devices and browsers
It's essential to test mobile websites created with JQuery Mobile on different devices and browsers to ensure maximum compatibility. You can use emulators or simulators to reproduce the behavior of different mobile devices, or you can test directly on physical devices. We also recommend testing on different browsers, such as Chrome, Safari, Firefox and Internet Explorer, to check compatibility and page rendering.
