CSS styling makes it easy for almost any DOM node to render as almost anything.
To give one trivial example, a paragraph element can be turned into a table
cell with "display: table-cell" or removed from rendering entirely with
"display: none". The main reason to have a separate render tree is that the
structure and classes of the render tree nodes can reflect the
post-style-computation decisions of what will actually be rendered, which can
be quite a bit different from the structure of the document itself. The DOM
tree nodes represent the document’s structure.
