Screenfly is a free-to-use web application that can display any website on different device screens and resolutions.

It uses a proxy server to mimic devices and supports the most-used ones under tablet and mobile categories.

Also, TV and desktop categories helps viewing websites according to the selected screen-sizes of the devices.

Harry Roberts of CSS Wizardry recently launched a flexible and production-ready CSS framework, inuit.css, which aims to solve real problems and remove the boring, repetitive jobs that development sometimes brings.

Besides desktop browsers, the framework also works on mobile and tablet devices with minimum effort.

inuit.css is a single-file-framework and makes very few decisions and puts you in total control.

It embraces progressive enhancement and the features are compatible by IE7+, leaving IE6 behind.
