Stack Overflow is a really neat "question and answer" site where you can ask all sorts of web-related questions and receive responses from the community. If you've dabbled in web development or coding, you may have been to the Stack Overflow website.
Stack Overflow is not just for coders though. If you are on a website and think, "I wonder how they make the menu do that," or "that's a great feature, I wonder how it works," then try asking the community on Stack Overflow. The answer might be easier than you thought!
