This project was a first attempt at creating an app with a desktop-like feel, complete with zooming/scaling capabilities for focusing individual elements or groups of elements. It does so using jQuery to toggle CSS classes containing the transform: scale property.
Each .grid-container element may contain a div.title and div.content. Cells are placed in the .content divs. Grids may be nested as deeply as you like, though the headers become illegible after one or two levels, depending on the number of cells.
