# Resizable agent window

The cobrowse session typically runs from two different devices. The screen display of these devices might differ depending on the devices used for cobrowsing. For example, an agent uses a desktop screen whereas the customer uses an iPad.

In order to provide a common user interface experience, and to ensure that both the parties see the same fields on their screens, the DOM or screen viewable area of the agent screen is fluid in nature. Once the cobrowse session starts, the viewable area of the screen of the customer is drawn as per exact size in the agent view pane. During the session, if the customer resizes the screen either by changing window dimension or by the virtue of device rotation, the agent viewable area adjusts accordingly. The agent might see a very small view pane in case the customer is on a device with the touchscreen device keypad on, but the area on the form that is edited is always visible to the agent. Once the keypad resizes back, the agent screen also resizes to the customer viewport.
