The Style Manager 
The Style Manager is the central hub for editing and creating vBulletin styles and their constituents. From here you can control every aspect of the way your vBulletin installation appears to your visitors, from simple color and font changes right through to fundamentally altering the layout of the board by editing templates.

The image above shows the Style Manager as it would appear immediately after a new vBulletin installation. Looking at the Style Manager from left to right, various controls are visible.
