Microsoft has posted a whitepaper titled "Introducing Internet Explorer 4.0's Dynamic HTML" that discusses the upcoming Trident technology in the company's new Web browser. Dynamic HTML introduces a new Object Model for scripting languages and provides developers with more control over the appearance, interactivity and style of Web-based content. Dynamic HTML is also fully compatible with the W3C Cascading Style Sheets (CSS).
If you develop Web sites, this whitepaper is a must-read. A version in Word document format is also available.
