DevTools Tips: Device Mode

Published on

With DevTools, you can test how your website behaves and performs on any device without having to browse it on real devices.

Use the Device Mode to simulate a mobile viewport and configure it:

  • Set the device dimensions in various ways or use the presets.
  • Switch between landscape and portrait orientations.
  • Debug the @media min- and max-width breakpoints.
  • Choose a device to simulate or configure a custom one.
  • Simulate your page's performance on mid-tier and low-end devices by throttling CPU and network speed.
  • Enable offline mode to test your website's offline content, if any.
