Explain the viewport meta tag and its importance
← All CSS3 questions
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).
