In the character 角 in traditional Chinese, as well as in Japanese, Korean and Vietnamese, the central vertical stroke does not extend below the last horizontal line, the one formed by the seventh, last stroke. This creates an appearance roughly equivalent to 土 enclosed in the top part of 冂.
However, in simplified Chinese, the central vertical stroke in 角 extends to the bottom of the character (as in 用). This difference applies to all simplified Chinese characters containing this radical.
Note that the Chinese and Japanese stroke order is slightly different for the fifth and sixth strokes, as illustrated in the animations above.
