W3Schools is a tutorial site which provides "well organized and easy to understand online Web tutorials based on W3C Web standards." It has a very basic web-based approach to teaching.

This site defines a useful organizational framework for navigation and supports interactive samples. However, it provides no tutorial authoring functionality and is therefore insufficient for the CSTutor's needs.

Good Features:

• provides a simple framework for browsing
• provides Previous and Next links on every tutorial page
• where script examples are present, provides interaction - clicking the link brings up a new page that allows the script to be edited and displays the result
• displays the tutorial "timeline" in the navigation bar and highlights the current step
• allows for a quiz at the end of a tutorial - shows the questions as well as any incorrect answers, but does not display the correct answer or provide a link to the corresponding tutorial section
• provides a site-wide search option
