Question-and-Answer Site
A website organized around people asking questions and receiving answers from other users.

Context
Often shortened to Q&A site, a question-and-answer site usually gives each question a page where answers can be read together. Features such as topic labels, voting, accepted answers, and moderation help organize the knowledge.
Stack Overflow is a well-known example focused on programming. My Mayvene project explores questions, answers, and how a community can build useful knowledge.
Examples
- Someone asks how a CSS layout works, and the answers explain different approaches with examples.
