If you're a desktop publisher, you would be familiar with the term leading. Applying leading to a paragraph of text adds space in between each line.
To apply leading (or line-height) in CSS
There is no "CSS leading" property - the CSS specification uses the line-height property to apply leading. Leading gives the impression of lines of text being closer together or further apart.
You can also use the CSS
font property to set the leading/line-height property values.
