.stackContent nodes always wrap content. They are block level and therefore are the full width of their parent.

The next three nodes are .stackAuto which applies width:auto to them. If you reduce the window width they will automatically stack vertically:

.stackAuto .stackContent
.stackAuto .stackContent
.stackAuto .stackContent

The next two nodes have vertical-align:middle applied to them:
.stack1of2 .stackContent
.stack1of2 .stackContent
.stack1of2 .stackContent
.stack1of2 .stackContent
Here are the rest of the available width divisions. You'll see .stack1of6 in the CSS but I never use it because 1/6 width nodes are severly affected by the decimal rounding error in some browsers, especially when nested.

Just to prove the stacks are infitely nestable i've nested the markup from above into smaller divisions:

.stackContent nodes always wrap content. They are block level and therefore are the full width of their parent. In this case the parent is the outer wrapper of the entire stack which is also a

The two nodes below are also .stackAuto which applies width:auto to them. If you reduce the window width they will automatically stack vertically:
