About The Mobile First Movement
Responsive web design is a web design approach aimed at crafting 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 mobile phones to desktop computer monitors.
A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids,flexible images, and CSS3 media queries, an extension of the @media rule.
Audience and Device Aware is an approach aimed at ensuring that a site is optimised to deliver what a user wants and that works effectively on the device being used to access the site. Unlike Responsive web design (RWD), which crafts a site visually for a range of devices, ADA aims to reflect the many different elements that enhance and impact on the performance and usability of a site.
The predominant application for the ADA approach is for mobile and smaller screen devices. The principle truly sees the adoption of a “mobile first” strategy and focuses on the performance of a site and value that it delivers to a user and the business.
