There are some points that make RWD stand out of the crowd of web designers.

Limited weight of graphics

With high optimisation and style tricks we're able to set up very lightweight sites but using a pleasant and original design. A general page weights less than 100kb, often around 30kb (5 seconds on a 56.6 modem)

Standards and platforms

We tend whenever possible to adhere to W3C standards. When not possible to get special features we check the site over the commonest browsers to get it look the same to each visitor.

Consulence on graphics

The big challenge is to link our clients' graphic wishes with web limitations, the target being an accessible and usable layout over charming graphics.
