Is the approach that suggests that design and development should respond to the user 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. As the user switches from their laptop to iPad, ext, the website should
automatically switch to accommodate for resolution, image size and scripting abilities. In other words, the website
should have the technology to automatically respond to the user preferences. This would eliminate the need for a
different design and development phase for each new gadget on the market.
