What’s New

Preview your designs in standard screen resolutions, or use media queries to define resolution. When testing for devices that change page orientation based on how the device is held, use the landscape and portrait options during preview. For more information, see Designing for multiple screens and devices.

Use media queries to customize the appearance of your site for different screen resolutions. For more information, see Creating media queries (CS5.5 and later).

Quickly design a web application that works on most mobile devices using the jQuery Mobile widget. For more information, see Creating web applications for mobile devices (CS5.5 and later).

Package your web applications in Dreamweaver, and deploy them to Android™ and iOS-based devices. For more information, see Packaging web applications.

Dreamweaver supports code hinting for HTML5, CSS3, and jQuery.

Starter layouts are also available for building HTML5 pages from scratch. Dreamweaver supports the HTML5 feature to embed videos in HTML pages. For more information, see Embed videos in web pages (HTML5).

The CSS panel has been enhanced to support commonly used CSS3 properties. For more information, see Code hints and Enhancements to CSS3 support in the CSS styles panel (CS5.5).

Transfer data using FTPS. FTPS (FTP over SSL) provides both encryption and authentication support as compared to SFTP that supports only encryption. For more information, see FTPS connections (CS5.5).

Create standards-compliant HTML and XHTML pages using the W3C validator in Dreamweaver. For more information, see Validate documents using W3C validator (CS5.5).

Dreamweaver CS5 integrates with Adobe BrowserLab, one of the new CS Live online services, which provides a fast and accurate solution for cross-browser compatibility testing. With BrowserLab you can preview web pages and local content using multiple viewing and comparison tools. See BrowserLab.

Adobe Business Catalyst is a hosted application that replaces traditional desktop tools with one, central platform for web designers. The application works hand-in-hand with Dreamweaver, and lets you build everything from basic data-driven websites to powerful online stores. See http://www.adobe.com/go/business_catalyst_get_extension_en.

The Dynamically-Related Files feature lets you discover all of the external files and scripts necessary to assemble PHP-based Content Management System (CMS) pages, and displays their filenames in the Related Files toolbar. By default Dreamweaver supports file discovery for the Wordpress, Drupal, and Joomla! CMS frameworks. See Open Dynamically-Related Files.

Live view navigation activates links in Live view, allowing you to interact with server-side applications and dynamic data. The feature also allows you to enter a URL to inspect pages served from a live web server and edit pages you have browsed to if they exist in one of your locally defined sites. See Previewing pages in Dreamweaver.

PHP custom class code hinting displays the proper syntax for PHP functions, objects, and constants, helping you type more accurate code. Code hinting also works with your own custom functions and classes, as well as third-party frameworks, such as the Zend framework.

The newly redesigned Site Definition dialog box (now the Site Setup dialog box) makes it easier to set up a local Dreamweaver site so that you can start building web pages right away. The remote server category lets you specify your remote and testing servers in one view. See Set up a local version of your site and Connect to a remote server.

The Site-specific code hints feature lets you customize your coding environment when working with third-party PHP libraries and CMS frameworks such as WordPress, Drupal, Joomla!, or other frameworks. Theme files for blogs and other custom PHP files and directories can be included or excluded as sources for code-hints. See Site-specific code hints.

Dreamweaver CS5 expands its support for Subversion, allowing you to move, copy, and delete files locally, and then synchronize changes with your remote SVN repository. The new Revert command allows you to quickly correct tree conflicts or rollback to a previous version of a file. Additionally, a new extension allows you to specify which version of Subversion you would like to work with on a given project. See Use Subversion (SVN) to get and check in files.
