What new style of dynamic contrast did composers begin to write into their scores during the classical period?

The Classical musical period saw the standardization and refinement of dynamic contrast, using dynamics such as crescendo, decrescendo, and sforzando, marked with terms like "f" (forte), "p" (piano), "mf" (mezzo-forte), "mp" (mezzo-piano), "sforz" (sforzando), "dim" (diminuendo), and "cresc" (crescendo) in their scores to indicate specific volume changes throughout a piece.
