James and Jessi are both developers working on a mobile website for a customer. James develops the site using traditional HTML5, CSS, and JavaScript while Jessi uses the FITML platform. Over time, as new device and browser updates are released, James' site requires extensive reworking to maintain compatibility while Jessi's site remains updated automatically through FITML. The customer grows frustrated with the extra costs from James' site, while Jessi is able to take on new projects smoothly and ensure compatibility across all devices.
