User agent (such as browser) selects the root element as Containing Block (called the initial containing block). When the child of HTML does not have other contained blocks, it will rely on the initial contained block to position,
initially contains the size of the block? That is, the viewport size, the height does not increase as HTML increases.

The elements that are not absolutely positioned include blocks of the nearest block-level ancestors.
The same is true for floating elements, starting from the content boundary.

The absolute element is included by the nearest Position is not STATIC.

In fact, this is more complicated, and it is necessary to consider the absolute element containing blocks to be built or block-level elements.
