Flexible Browser Targeting and Validation Some projects require HTML code that conforms to certain standards or limitations. You might be writing code that needs to run well on a legacy browser or a mobile device, or you may need to adhere to an XHTML or other coding standard. Visual Studio 2005 lets you target your code to all the major browser versions and XHTML standards right out of the box. Your HTML will then be validated in real-time as you type in the source editor. Tooltips identify and explain HTML code that is invalid for your chosen target, and validation errors are summarized in the Task List window. If your project has special coding requirements, you can easily customize and extend the pluggable validation rules in Visual Studio 2005 to meet your particular needs. Target different browsers and standards and let Visual Studio 2005 validate your HTML code.
