line-height: normal |	multiplier | value | percent
Value normal forces a browser to calculate distance between lines automatically. Any number of more zero is perceived as a multiplier from a font size of the current text. For example, value 1.5 determines one-and-a-half line spacing. Any length units in CSS are accepted as values — for example, pixels (px), inches (in) are accepted, points (pt), etc. It is allowed to use percentage record. In this case the font height undertakes 100 percent.

    line-height: 1.5;
