Responsive web design (RWD) is an approach to web design aimed at allowing desktop webpages to be viewed in response to the size of the screen or web browser one is viewing with. In addition it's important to understand that Responsive Web Design tasks include offering the same support to a variety of devices for a single website.
Responsive design is about more than just layout; it’s about designing for the Web, which means, mostly, for people with browsers. And that’s just about everything we know about the people who visit our websites: they are probably using a browser. All the rest we just don’t know.
Up until not so long ago, we used to base our designs on some rather general assumptions about screen size and input type. With the rise of devices with various screen sizes and alternative ways to interact, these assumptions have turned out to be unreliable. We need to upgrade the defaults that we use when we start designing our websites.
Bad Design:
The way we designed our websites until recently was by putting a header with the logo and navigation at the top, putting the subnavigation on the left, putting some widgets on the right, and putting the footer at the bottom. When all of that was done, we’d cram the content into the little space that was left in the middle. All of the things we created first — the navigation, the widgets, the footer — they all helped the visitor to leave the page. But the visitor probably wanted to be there! That was weird. It was as if we were not so confident in our own content and tried our best to come up with something else that our guests might like.
But rather than pollute the page with all kinds of links to get people out of there, we should really focus on that thing in the middle. Make sure it works. Make sure it looks good. Make sure it’s readable. Make sure people will understand it and find it useful.
