line-height
CSS line-height Property
The line-height property defines the line-height. There are three situations:
On block level elements, the line-height property specifies the minimal line-height of line boxes in the element.
On non-replaced inline elements, the line-height property specifies the height which is used in the calculation of the line box height.
On replaced inline elements just like buttons or other input elements, the line-height property does not affect.
Negative values are valid.
The default line-height is about 110% to 120% for the majority of the browsers.
The line-height property sets the leading of lines of a text. If the line-height value is greater than the font-size value of an element, the difference will be the leading of text.
The line-height property has no effect when applying to inline elements: such as images, buttons, etc.

Line-height property for different purposes
Line-height property for different purposes
The line-height property can be used for creating different interesting styles. For example, you can use the line-height property to give each line of the text a different color. Here you may use a linear-gradient () with color-stops. Or you can use this property for putting lines between texts with the help of repeating-linear-gradient().
