The use of mobile devices to surf the web is growing rapidly, but unfortunately 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 screen.
There is a lot of different screen sizes across phones, “phablets”, tablets, desktops, game consoles, TVs, even wearables. Screen sizes will always be changing, so it’s important that your site can adapt to any screen size, today or in the future.

Responsive web design, originally defined by Ethan Marcotte, responds to the needs of the users and the devices they’re using. The layout changes based on the size and capabilities of the device. For example, on a phone, users would see content shown in a single column view; a tablet might show the same content in two columns.

Almost every new client these days wants a mobile version of their website. But most of the time Responsive Design is the resque. This not only enhances and customizes the the end user experience based on his device, but also decreases development time because no need to create a different website/app for every platform.
Here at e-Sealed we build responsive websites for our clients to succeed in the mobile age, and also to decrease the costs to reach their clients on most platforms significantly.
