How different types of elements behave
Block level elements:
Default stacking behavior:
This is a block level element which is stacked on another:
This is a block level element which has another block level element above it!
Block level element with a child
This is a block level element INSIDE another block level element
Block level element with a multiple block level children
This is a block level element INSIDE another block level element
So is this one, and it has the other child stacked on top!
Block level element with an inline child
Some of this text is surrounded by an inline element, which is not
the same as a block level element.
Inline elements
The following has a series of inline elements; this contains
an inline element with a child inline element.
