W3Schools is a web developer information website, with tutorials and references relating to HTML, CSS, JavaScript, PHP, SQL, Bootstrap, and jQuery. Created in 1998, its name is derived from the World Wide Web, but is not affiliated with the W3C (World Wide Web Consortium). It is run by Refsnes Data in Norway. W3Schools presents thousands of code examples. By using an online editor, readers can edit examples and execute the code in a sandbox.  (https://en.wikipedia.org/wiki/W3Schools)
