# CoursesWeb Forum

> CoursesWeb Forum is a question and answer community about learning web development: HTML, CSS, JavaScript, PHP, MySQL, Node.js and AI coding help.

Threads open with a short, self-contained answer, then the discussion. Posts marked Staff are written by the forum team and cite primary sources. Dates on every post are machine-readable. Each thread is also available as Markdown: replace the trailing slash of its URL with `.md`.
