Here’s a quick reference on how to style all of your font properties (and one text property: line-height) in one rule.
font: weight | variant | style | size/line height | font-family
font: bold small-caps italic 1em/1.25 Georgia, "Times New Roman", Times, serif;
For this to work, you must include font-size and the font-family (in that order). They must also be the last two values listed. If you leave out values, those values will render in their default state, ignoring inheritance and other group selectors.
Line height is optional. Note that line height doesn’t have a unit. Eric Meyer explains why.
