Microsoft Live Labs has announced a new project called “Web Sandbox” lead by Scott Isaacs. The sandbox takes HTML, CSS, and JavaScript, and puts it in an isolated box. The goal is a little like Caja, AdSafe, FBJS, and other solutions that try to make JavaScript execution more secure in some way.

The Web Sandbox explores how to advance the Web Platform to improve security, isolation, and quality of service protections for your web site and users.

The Web Sandbox project has a wide scope. The HTML elements and attributes, CSS selectors and properties, JavaScript constructs and statements, and all the DOM APIs eventually will need to be evaluated and reviewed. While daunting, this is a not only a challenge that's worth the effort, but also one that needs to be tackled properly. This area of the site is a set of living documents that will be updated and expanded over the coming weeks and months.
