This is a simple tip that can help you reduce your style sheet size. Take a look at this CSS portion:
font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 1.1em; font-weight: bold; font-style: italic; line-height: 1.5em; font-variant: uppercase;
All these properties can be condensed into a one row expression using this syntax:
font: fontSize/lineHeight weight style variant family;
See the example below:
font: 1.1em/1.5em bold italic uppercase Arial,Verdana,Helvetica,sans-serif;
Just remember that this syntax will only function if you specify both font-size and font-family.
