Responsive design responds to the environment. You can have an adaptive layout which are multiple fixed width layouts or you can have a responsive layout which are multiple fluid grid layouts. This kind of design is new but growing and much needed. With all the smart phones, tablets, iPads, and computers as well, we need to be able to have different versions of the same website for each screen size. Mobile web is important because majority of people have smart phones and accessing the internet on a mobile device should be easier. I think using the responsive design techniques such as making one website and having it adapt and respond to its environment its the best way of making mobile web more friendly and easily used. I also think that it will make mobile web more widely used by users because it would and is becoming easier to use.
