# # Make the Web Viewer Adaptive to the Device

Foxit PDF SDK for Web can allow the viewer to be adaptive to the device (desktop or mobile), which means if you access the web viewer in your desktop browser, it will be present using the desktop UI layout, and if you access the web viewer in your mobile browser, it will be present using the mobile UI layout. To make the project adaptive to the device, you may refer to the example adaptive-to-the-device.html and Appearance for details.
