css letter-spacing property syntax
Function: letter-spacing property increases or decreases the space between characters (character spacing).
Description: This attribute defines how much space is inserted between text character boxes. Because character glyphs are typically narrower than their character boxes, specifying a length value adjusts the usual spacing between letters. Therefore, normal is equivalent to a value of 0.
Note: All browsers support the letter-spacing attribute. The attribute value "inherit" is not supported in any version of Internet Explorer (including IE8).
