Responsive Web design is the approach that suggests that design and development should respond 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. It is important because more and more people use mobile than desktop nowadays. A breakpoint is a place in a computer program where the sequence of instructions is interrupted, especially by another program or by the operator.
