Hi Robin!
Detectiveland has two main panes (or columns) situated side-by-side on a wide screen (room descriptions and actions are on the left while the inventory, exits, and other interactive components are on the right). The Party Line has one main section of block elements displayed one after the other.
How can I edit my own CSS (which I am comfortable accessing and altering for Gruescript) to closer resemble Detectiveland's layout (two side-by-side panes) rather than The Party Line's layout (a single vertical pane)?
