This World of Warcraft - Mists of pandaria template uses the current standard of 1200 pixel width for content, although it is optimised for screens running at 1080p (1920 x 1080).
When viewed on a screen smaller than 1200 pixels wide, the content will re-arrange itself vertically, and scale to full screen width so that the viewer does not need to scroll left and right to view the website content.
You can see how this responsiveness works by visiting our Template Demonstration Site
If you are viewing this on a screen with a larger width than 1200 pixels, you can see this responsiveness in action simply by making your browser window smaller.
In order to view different Templates available for World of Warcraft, simply use the 'Template Selector' on the left of the screen on the Template Demonstration Site to switch between templates - the selector is page-dependant, so if you switch pages to view the themed forums, you will need to reselect the template.
By default, there are 25 available module positions, but you can place more than one module in most of the positions, greatly increasing the actual amount of module positions.
There are 5 module styles available in the Mists of Pandaria Template, as can be seen in the image below.
These styles can be applied by typing ' styleX' into the 'Module Class Suffix' box under the Module > advanced option.
Simply replace the 'X' with the number of the style you wish to use.
**please note the leading space before 'styleX'
