Block Variations
Block Variations allow for the individual styling of each block within a region, without it being global. Code wise, this is achieved by adding a class into the block code which loads from the Block Class Suffix field in the Block Manager. The theme CSS adjusts accordingly.
There are 14 suffixes: bg1-5, title1-5, flush, flushtop, flushbottom & basic.
The BG and Title suffixes load their coloring from the Color options of the theme, if blue is the header color, bg1 will be blue. bg1 loads the header color; b2 loads the feature color; b3 loads the main surround color; b4 loads the main body color; and b5 loads the footer color. These are available in all the main body areas: MainTop, MainBottom, ContentTop, ContentBottom and Sidebar. The suffixes will work in Top, Header, Bottom and Footer, but may not be as aesthetically pleasing, depending on your color combination.
Flush will disable all padding and margin to the block for a tighter fit, with FlushTop and FlushBottom disabling the margin/padding for the Top/Bottom parts of the block respectively. Basic removes all image based styling from the block.
