What is Responsive Web Design?
Design and development that responds to the user’s behavior and
environment based on screen size, platform and orientation.
The practice consists of a mix of flexible grids and layouts, images
and an intelligent use of CSS media queries.

Mode of Usage
Mobile is a user state, not a device, and usage is a more influential factor on interface design than
browser width, say.
Design with attention to things such as:
• search style*
• duration of usage
• lean back vs on-the-go use
• single- vs multi-user
• user intent
* Average mobile search on has roughly double the keywords than the average desktop search: the interface is smaller but mobile
searchers are more task-focused and highly specific in what they’re seeking.
“70% of PC search tasks are completed in one week, while 70% of mobile search tasks are done in one hour.”

Context Awareness
An aspect of focussing on the user is consideration for the context and
surroundings of usage, this should cover all aspects of the context of that usage:
• noise level
• privacy
• light level
• bandwidth
• constancy of connectivity; including offline usage
• location awareness and location signal strength
• accessibility

The Device
The capabilities of the device being employed is more important than its dimensions.
Detect features rather than try and adapt to specific devices.
As device proliferation becomes even more of a problem to manage, detection by
model is untenable so favor feature provisioning by device capability including:
• input method
(i.e. five-key, keyboard/mouse, rollerball, touch, multi-touch/gesture, facial recognition, body)
• screen resolution
• device/screen size
• location awareness
• standards support
• device functionality
