Re-explain

The viewport meta tag controls how mobile browsers render pages:

<meta name="viewport" content="width=device-width, initial-scale=1.0">
  • width=device-width: Uses device's actual width
  • initial-scale=1.0: No initial zoom
  • user-scalable=no: Prevents zooming (avoid unless necessary)

Without this tag, mobile browsers use desktop viewport width (usually 980px).
