In the early days of web site design, there was a need to manipulate HTML code and CSS layouts for proper viewing by different web browsers on desktops and laptops only. Today, there is a need to design websites that are optimized for viewing across all devices and platforms. Inflexion Interactive is a company that specializes in Responsive Web Design solutions that include custom development optimized for desktop computers, laptops, smartphones and tablets. This company can develop mobile marketing solutions that include apps for opening a website with the tap of a touchscreen on a smartphone. The key element in Inflexion Interactive's Responsive Web Design is creating a single functional website that can be viewed by multiple devices. Other developers often need to create multiple websites to accommodate all possible devices such as mobile phones and tablets. The RWD technology integrated by Inflexion Interactive automatically displays content and layouts according to the type of web browser and device that is detected. A single website with RWD technology can be displayed differently according to the screen resolution of a detected device. A flexible grid layout essentially scales all content up or down based on several factors associated with a website's visitor.
