The line-height property in CSS is used to set the amount of space used for lines, such as in the text. Negative values are not allowed.
Syntax:
line-height: normal|number|length|percentage|initial|inherit;
Property values:
- normal: This mode represents the normal line height. This is the default value.
- initial: This mode is used to set this property to its default value.
- number: This value is a unitless number multiplied by the current font-size to set the line height. In most cases, this is the preferred way to set line height and avoid unexpected results due to inheritance.
- length: In this mode a fixed line height is specified.
- percentage: This mode is used to set line height in percent of the current font size.
Example: In this example, we are using the line-height: normal; property.
