July 2014 Update: Added a note about IE8, a known browser that does not support responsive design technology.

Summon 2.0 uses a Responsive Design layout so that the Summon service "responds" to the user's screen size and provides an effective user experience.

In addition to providing layouts for using Summon on a mobile device, the Summon service also responds to varying desktop/laptop sizes by providing a narrower third column for the Explorer pane (displays Topic Explorer and Item Preview) for desktop/laptop screen widths of 1280 pixels and less.

Specific details on the layouts for mobile and desktop/laptop screens are as follows:

	Screen Width	Devices
1 Column Layout	Less than 701 pixel width	Most mobile devices
2 Column Layout	Greater than 700 pixel width Less than 1025 pixel width	iPad (Portrait screen orientation) Large phone (Landscape screen orientation) Low resolution PCs
3 Column Layout (slim 3rd column)	Greater than 1024 pixel width Less than 1281 pixel width	Desktop / Laptop iPad (Landscape screen orientation) Most tablets (Landscape screen orientation)
3 Column Layout (full 3rd column)	Greater than 1280 pixel width	Large desktop / laptop
