Responsive web design crafts sites to provide an optimal viewing experience—easy reading and navigation with a minimum of resizing, panning, and scrolling—across a wide range of devices (from computer monitors to mobile phones and tablets).
A web site with a responsive design adapts the layout to the viewing environment by using fluid, proportion-based grids (we use bootstrap framework), flexible images, and CSS3 media queries.
The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points.
Flexible images are also sized in relative units, so as to prevent them from displaying outside their containing element.
Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, most commonly the width of the browser.
A responsive web design will enhance the usability of your site for mobile device users. Your customers will no longer have to scale your page larger to read the content on your site. With mobile users growing at a double digit rate every year, more and more people are browsing websites from their phones and tablets. Currently the average visits to the web from mobile devices is 40%! That means, if you lack a mobile friendly site, as many as 40% of your visitors will click away in favor of a competitor whose site they can browse easily on their device.
