Define line spacing

Could it be done?

[henry0]

Is it possible to define line spacing in order to respect the following proportion:(120% of font size)

Line spacing=(font-size/100)*120

[Span]

It is called line-height:

p {
font-size:10px;
line-height:120%;
}

or, shorthand:

p {
font:10px/120% verdana,sans-serif;
}

Many Thanks :)
Easy enough when you know your CSS!
