What it does
W3Schools provides tutorials, topic references and exercises covering web development and programming languages.
W3Schools works well beside a small practice project. Read a tutorial topic, try the corresponding exercise, then keep the reference nearby when you forget a keyword or element. Its broad subject menu supports quick switching between HTML, CSS, JavaScript and SQL. Following one tutorial in order will be easier than jumping among all those menus at once. The tutorials are free; paid courses and Plus features are separate offerings.
