"XSS" is a pretty broad range of attacks. HTML has a number of features 
designed to prevent XSS attacks, for example the origin security policy, 
the <iframe sandbox> feature, and the text/html-sandboxed MIME type. 
Others have also been proposed, such as a syntax to embed text as base64 
data safely.

HTH. If you have any specific questions please don't hesitate to raise
