This space inherits the consistent characteristics of the space family: it is transparent. This space has a very stable characteristic.
means that the width it occupies is exactly 1/2 the Chinese width, and it is basically not affected by the font.
3. " "It is called "full-width space", and its full name is Em Space. Em is the measurement unit of typography, which is equivalent to the currently specified number of points. For example, 1 em in a 16px font is 16px. This space also inherits the consistent characteristics of the space family: it is transparent. This space also has a very stable characteristic.
