After successfully creating a consistent group of webpages that display properly in IE, Mozilla, Opera, and Chrome, and passing validation on the W3C online validators, I encountered an issue when integrating the HTML code into ASP.NET. Specifically, the design was negatively impacted, especially when using divs with position absolute. Even though my HTML code remains clean and no controls have been added to the webpages yet, Visual Studio.NET 2008 SP1 seems to be causing this problem.
Interestingly, while working with ASPNET MVC previously, I did not face these kinds of issues.
Thank you
