• An element whose representation is outside the scope of CSS, i.e., an external object whose representation is independent of the CSS formatting model. Put in simpler terms, a replaced element is an element whose contents are not affected by the current document’s styles. The position of the replaced element can be affected using CSS, but not the contents of the replaced element itself. Some replaced elements, such as iframe elements, may have style sheets of their own, but they do not inherit the styles of the parent document. Typical replaced elements include iframe, video, embed, and img. ← MDN Web Docs
