When set to Responsive Mode, and totally automatically, will analyse both the width and the height of your page and fit the content appropriately.
What this means is that the responsive column widths are always respected and no scaling will take place until the columns start to shrink in width.
When the columns reach the mobile breakpoint where they will stack on top of each other an get wider, Intelliscale will recognise this and scale accordingly.
On mobile screens, the presentation of your site can dramatically alter. Everything is there, in one tall column. Responsive mode solves this problem by scaling with the screen height at this point, ensuring that what was intended to be in view, is in view.
