Responsive Web Design (RWD) is a term that describes the concept of building a website design in a way that allows the layout to change depending on what screen resolution the viewer has. For example, an advanced four-column layout that looks great with a screen width of 1280 pixels (or higher) could be simplified into a more simple 2-column layout on screens with 1024 pixels width – and further down to a single column on small screens such as those on smartphones or small tablet computers. It is an alternative to building separate mobile sites, and when done in a good way it can look really beautiful.

Responsive website design term is related to the concept of developing a website design in a manner, that helps the lay out to get changed according to the user's computer screen resolution. More precisely, the concept allows for an advanced 4 column layout 1292 pixels wide, on a 1025 pixel width screen, that auto-simplifies into 2 columns. Also it suitably fixes on the smartphone and computer tablet screen. This particular designing technique we call "responsive web design".

Fixed Width vs Responsive Web Design
Fixed width designs are easier to conceive and build in most cases, but they don't work well when the screen size is a drastic change from the design. Because of this, mobile device makers scale most sites down to size, which leaves the content too small to read until the user zooms in. That experience was great when the iPhone and other mobile phones and devices started to play nice with "the real web", but it's hardly a native experience. And that's just the mobile device issue.

Tablets are coming out in a variety of sizes, laptops are getting both smaller and larger, and even our old friend, the desktop, is growing to larger screens and resolutions. Given all these new display options, designing solely for 960px seems a little silly, right?

It is a completely different designing version than the traditional web designing. Responsive web design images are primarily fluid images that can be replaced by context aware images, an updated version for better designing. This particular technique serves the purpose of responsive designing in true sense as the images serve at different resolutions, ranging from larger screens to smaller ones. The scaled images appear to change fluidly with the help of updated developer tools and coding languages, allowing designs to look sharp in every context. Responsive web designing is remarkably different from traditional designing in terms of technical and creative issues and a careful use of this can do wonder while designing.

Responsive web design is drifting away from the pool of passing fads and rapidly entering the realm of standard practice. In fact, the magnitude of this paradigm shift feels as fundamental as the transition from table based layouts to CSS. Simply put, this is a very different way of designing websites and it represents the future. Check some Responsive Web Design Works:
