Yes, it is. If you haven’t disabled the Responsive Design option, found under Options > Responsive, then your site is already responsive, and will alter its layout when it is viewed in tablet or mobile view, according to the options and breakpoints you set. For example, a Container displaying two 1/2 Columns on Desktop will, by default, display them as 1/1 Columns when on a Small (Phone) device, to compensate for the narrow viewport.
There are many Responsive options you can set in Avada, and you can set your own breakpoints for several areas of the layout. Please see the Responsive Options in Avada video for full details on that. But this new feature offers you much greater granular control with your content, and works in conjunction with the Avada Options to give you the freedom to decide exactly how you want your Columns to display on both Medium and Small size screens.
So now, if you want 1/2 width columns on Small Screens, that’s no problem. You can even drag and drop containers to change their order on various layouts. In short, you can have three completely different layouts for the same Containers and Columns, giving you all the flexibility you need for responsive design.
