Framework
DropInn is built using the CodeIgniter framework. CodeIgniter is an Application Development Framework – a toolkit – for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task. CodeIgniter is a dynamically instantiated, loosely coupled system with high component singularity. It strives for simplicity, flexibility, and high performance.
UI Model
Layouts: A layout is a component which wraps and places multiple views or nested layouts on a page. The style sheets are in the folder ‘css’ located in the root folder. Similarly the style sheet files for the other colors green, orange, pink, red and yellow are located in css_green, css_orange, css_pink, css_red folder and css_yellow folders. Logo images are stored in the ‘logo’ folder in the root. The video for the home page is located in the /uploads/home/ folder in the root. The video for the How it works is located in the /uploads/howit/ folder in the root.
