# Set the responsive viewport meta tag

Without the viewport meta tag, mobile browsers render pages at desktop width (typically 980px) then shrink them, making text unreadable without zooming.

## Quick Reference

- Add `<meta name="viewport" content="width=device-width, initial-scale=1.0">`
- Never use `maximum-scale=1` or `user-scalable=no` (breaks accessibility)
- Essential for mobile-responsive layouts

## Check

Verify that this HTML document includes a proper viewport meta tag for responsive design that controls how the page is displayed on mobile devices.
