How to Test Responsive Web Design Web Sites


Responsive Web design has become one of the hottest trends in 2013. This is due in part to the growth of smartphones and other mobile devices. More people are using smaller-screen devices to view Web pages.

Why Web Responsive Design?

Day-by-day technology in development environments the number of devices, platforms, and browsers that need to work with your site increases. Responsive web design represents a fundamental shift in how we'll build websites for the decade to come. The site wants to fit all small devices such as Mobiles and medium devices such as iPad Large One-like systems, one site for every screen.

What is Web Responsive Design?

  1. Responsive websites respond to their requested resolution environment.
  2. Adaptive (Multiple Fixed Width and Height Layouts) or Responsive (Multiple Layouts).
  3. Instead of responding to today's needs for a Desktop Web version adapted to the most common screen resolution, along with a specific mobile version (often specific to a single mobile device), the idea is to approach the issue the other way around: use flexible and fluid layouts that adapt to nearly any screen.

Web Responsive Design Core Concepts

Three key technical features are at the heart of responsive Web design.

  1. Media queries and media query listeners
  2. A flexible grid-based layout that uses relative sizing
  3. Flexible images and media, through dynamic resizing or CSS
