Don’t be fooled. Although the .5 might give the impression
that Dreamweaver CS5.5 is a point release, it’s anything but.
Dreamweaver engineers have packed a stunning amount
of new features into this version. To mention just a few,
library, the ability to see what pages will look like at different
screen resolutions without leaving the Document window,
support for jQuery Mobile widgets, and integration
of PhoneGap to build native apps for Android or iOS (the
operating system used in the iPhone, iPad, and iPod touch)....
Dreamweaver is the most powerful and industry-leading web design software that utilizes innovative web technologies such as HTML5, CSS3, and jQuery for web and mobile development. These technologies have radically reconfigured the process of designing the web content and function in the widest possible range of browsing environments ranging from desktops to mobile devices.
