Font - CSS Quick Syntax Reference Guide - page 47

font-style
font-style makes the text slanted. According to specifications, italic is a cursive
companion face to the normal face, and oblique is a slanted form of the normal face.
Both faces tend to be rendered the same way for most fonts, however.
font-style : inherit | normal | italic | oblique
font-variant
font-variant can be used to display text using small caps instead of lowercase letters.
A value of small-caps renders text in uppercase letters that are smaller than regular
uppercase letters.
font-variant : inherit | normal | small-caps
font-weight
font-weight sets the thickness of the font. The bolder and lighter values set the
thickness relative to the parent element, and the numeric values specify absolute weights.
The value of bold is equal to 700, and normal is the same as 400.
font-weight : inherit | normal | bold | bolder |
lighter | 100 | 200 | ... | 900
Even if several weight values can be specified, most fonts have only one type of bold,
as shown in the following example rendering:
lighter normal bold bolder 100 200 300 400 500 600 700 800 900
font
There is a convenient shorthand property named font that sets all the font properties in
one declaration.
font : inherit | <font-style> + <font-variant> +
<font-weight> + <font-size> / <line-height> +
<font-family>
The properties must be specified in the order listed previously. As long as this order is
kept, either one of the properties can be left out (except for font-size and font-family ,
which are mandatory). If a property is left out, the default value for that property is used,
which is to inherit the parent's value. The following example applies four font properties
to the paragraph element:
p { font: italic 50%/125% Verdana; }
