I have installed it on my Mac and it works great. It has code completion for HTML tags including attributes and CSS styles. It does syntax checks on the HTML during editing and highlights missing tags.
The Netbeans IDE comes with included Webkit browser for previewing your HTML apps, but recommeds the use of the Chrome browser which is supported through a separate extension that connects the browser with the IDE. For mobile HTML5 Netbeans mode makes use of Chromes ability to resize itself to a size of a mobile screen.
Also, in case you didn't know, the Chrome developer extension can emulate touch events.
Netbeans also has support for Java, PHP, XML and Groovy. Ruby support has been phased out apparently, Python is supported through a community extension.
If you are doing serious HTML5 development, be sure to give Netbeans 7.4 a try.Share on Twitter Share on Facebook
