This template has smart layout which will automatically adjust to Desktop, Tablet, and Phone screen width.
As you can see, when you are resizing the browser's window, then the layout will automatically be adjusted to its screen accordingly.
See also the Sidebar menu (Vertical Menu Layout) will automatically be collapsed in Tablet mode. When the Phone mode is being displayed, then the Sidebar menu will be hidden (off-canvas), and will be switched to the hamburger menu icon at the Header section.
Or, you may simply access this demo site from your Tablet device, or from your Phone.
