Yes, the browser does request HTML, CSS, and JavaScript from a server, but that doesn’t mean those languages are “backend.”

Frontend vs Backend isn’t about where the files live, it’s more about where the code runs.

Frontend (HTML, CSS, JavaScript)

  • Runs in the browser, on the user’s device.
  • The server just stores and sends the files.
  • The user’s browser does all the work of displaying the page, applying styles, and running JS.

Backend (Node, Python, PHP, databases, etc.)

  • Runs on the server, not in the browser.
  • It handles things like:
    • saving data
    • authentication
    • managing databases etc.
