W3schools

This is one of the best websites to learn computer science. You can learn through free classes, and if you want to receive the website's certificate, you must pay a certain amount. The tutorials on this site provide dozens and hundreds of examples and references for better learning and testing. In addition, many successful web developers have derived from the help of this site.

W3schools has a lot of tutorials on Html, CSS, PHP, javascript, jquery and several frameworks, as well as bootstrap. Not only that, but the site also has its online editor, allowing you to try out coding online without having to worry about installing separate text editors.

On the website, source code examples with explanations are freely displayed in English, most of which can be edited and executed interactively in the live editor. Other essential code elements are hidden so the user can focus on the displayed code. The tutorials are divided into individual chapters on development languages. Besides the tutorials being arranged scientifically, completely and accurately, W3Schools also provides a test code tool right on the page that allows you to see the results of your code immediately. A YouTube channel also covers and explains certain topics in web development and an Internet forum.
