Description:
The implementation height (line spacing) is essentially through the upper spacing, It is controlled by the bottom spacing, not the height of the text (the distance from the top edge to the bottom edge of the text). If the pixels of the text are 16px, the larger the line height is, the pixels of the text will remain unchanged, but the upper and lower spacing of the text will change.
