Your Guide to Using the Metropolis Style for phpBB.
Metropolis, the December 2012 phpBB club release, is an elegantly designed theme which combines simple color schemes and shades to complement an array of different content setups. It is an excellent style layer above the responsive core.
The style's content functionality is powered by RokBB 5 -- which has enhanced support for new community driven RokBridge, a bi-directional bridge for Joomla and phpBB. A standard assortment of features are also included.
NOTE: RokBB 5+ is required for Metropolis to work correctly. For more details on installing RokBB, please visit the Administrative Module installation guide. Also, this style presently only supports phpBB 3.0 and is not currently available for phpBB 3.1.
Similar to the Joomla version of Cerulean, there are 10 stylistic module class suffixes that add a unique style variation to the modules. These include: box1-5 and title1-4
Additionally, there are 25 structural suffixes which affect the layout and metrics of the modules. You can apply variations using RokBB framework. Suffixes can be applied to the forum categories list, forum topics list, forum posts list and various modules.
Extensive CSS styling gives user an ability to completely redesign the forum look, and achieve even the most sophisticated results.
