Some elements are treated as replaced elements only in specific cases:

Some form controls can also be replaced elements. The HTML spec says that an <input> element can be replaced, and <input> elements of the image type must always be replaced.

Using CSS with replaced elements

CSS handles replaced elements specifically in some cases, like when calculating margins and some auto values.

Note that some replaced elements, but not all, have intrinsic dimensions or a defined baseline, which is used by some CSS properties, such as vertical-align.
