The use of smart phones to surf the web is growing at an astronomical rate, but sadly much of the web isn’t optimized for those mobile devices. Mobile devices are often constrained by display size and require a different approach to how content is laid out on the screen.

There is a multitude of different screen sizes across phones, “phablets”, tablets, desktops, game consoles etc. Screen sizes will always be changing, so it’s important that your site can adapt to any screen size, today or in the future.
