Possessing extensive fluency in technical coding, the developers at Kohactive deliver optimized responsive web design (RWD) solutions for clients who want to have websites with cross platform compatibility. This Chicago based digital agency has programmers who understand how to apply HTML5, CSS3, Ajax, Javascript, PHP, Ruby on Rails and many other scripts and codes. Clean coding is used to build from scratch the back end foundation for mobile and desktop friendly websites. Landing pages are also configured to load automatically based on the type of platform that is detected on the user's end. Kohactive believes that a fluid layout is the highlight of any responsive web design project. For mobile versions, menu and side bars can be concealed in order to create more space for the display of main page content. Such menus could be configured to pop up with a single finger swipe on a smartphone or tablet device.
