The line-height property sets the height (leading) between lines of text in a block-level element such as a paragraph.

Values can be specified as a number of lines, a number of units (pixels, points, inches, centimeters, and so on), or a percentage of the font size.

Note: Negative values are not allowed.

The default value of normal is typically equivalent to 1.0 to 1.2 depending on the implementation.
