-    - A line-breaking opportunity exists after every preserved white space character, including between white space characters.
-    - Such preserved spaces take up space and do not hang, thus affecting the box's intrinsic sizes ({{cssxref("min-content")}} size and {{cssxref("max-content")}} size).
