Margins below the image

  • I found a margin with a certain width below the image, this margin is not like the margin between the paragraph and the paragraph.

    In the wordpress editor, if I type “shift enter” to wrap, there is no margin, but there is always some space under the image when I useing the JIN editor.

    What should I do to make the margins below the image as large as the paragraph, and enter “shift enter” to leave no space?
