reponsive layout example not responsive

Resizing the window in Chrome for PC works responsively, but does not work in mobile browsers.

Hi @woojin ,
In general, to provide the correct working on mobile you’ll need to:
a) provide mobile-compatible UI depending on screen size and/or the environment
b) enable the fullScreen mode:

if (webix.env.mobile) webix.ui.fullScreen();

Please check the following example:

It’s worked. Thank you.
