Introduction to Responsive Design
The way in which web sites are built has evolved over the past 20 years. The 1990s were dominated by web sites being built in tables, and although the cascading style sheet (CSS) specification was released in 1996, CSS didn’t really take center stage until mid-2003. This brought the launch of CSS Zen Garden, which demonstrated the power of CSS and how it could be used to completely restyle a site without even touching the HTML. With the subsequent rise in popularity of CSS, the development community standardized on targeting screens with a resolution of 1024 by 800, with larger screens being left with white space around the edges and smaller screens requiring scrolling. This was rolled out so that sites could be designed and built in a way that worked for the largest possible audience, as the majority of users were accessing them from the 1024 by 800 resolution.
