Dynamic Regions are the SooperThemes solution to complex layouts with dynamic content. In a normal region, if you put more than 1 block in a region, the blocks will stack vertically.

In a Dynamic Region, the blocks are stacked horizontally. On every pageload, the theme will see how many blocks are loading in an SOOPER Dynamic Region, and it will generate the CSS code that divides the horizontal space equally amongst the blocks that are loaded in the same region.

This layout technique is used in the regions called preblocks and postblocks.
