To the dismay of some web developers, Dynamic HTML appears difficult to develop and debug, as the different web browsers have varying degrees of support to the aforementioned technologies, and the huge range of screen sizes commonly used by clients means the end look can be fine-tuned only on for a limited number of browser/screen size combinations. However recent browsers (such as Internet Explorer 5.0 and up, Netscape Navigator 6.0 and Opera 7.0 and up) share a common Document Object Model which facilitates the use of this technology considerably, if one just writes web pages for these browsers.
