Use Chrome DevTools' Device Mode to build mobile-first, fully responsive websites. Learn how to use it to simulate a wide range of devices and their capabilities.
In a nutshell
- Emulate your site across different screen sizes and resolutions, including Retina displays.
- Responsively design by visualizing and inspecting CSS media queries.
- Evaluate your site's performance using the network emulator, without affecting traffic to other tabs.
- Accurately simulate device input for touch events, geolocation, and device orientation
