At NuStream, we create responsive, engaging, and intuitive websites. In a word, our system of design allows a website to change its layout, depending on how it is viewed. Text and images shift in response to the device type. Also, proximity to the device is a factor in creating a responsive design. Another key point — these factors combine as an example of user interface plasticity. Mobile web browsing has become the standard. Therefore, having a website optimized for mobile is critical to the success of a page.
