When specifying a font size, the value can have leading and trailing zeroes or they can be omitted completely. This does not affect the way the text is rendered.
Leading Zeroes
Zeros that appear at the beginning of a number are called
leading zeroes. Example:
font-size:0.5in - the first digit is a leading zero. In all major browsers, leading zeroes are optional. Therefore
font-size:.5in is a valid way of specifying font size. There can also be more than one leading zero.
Trailing zero
Zeroes that appear after a decimal point and at the end of the number are called
trailing zeroes. Example:
font-size:2.50em - the last digit is a trailing zero. In all major browsers, trailing zeroes are optional. Therefore, all the following declarations result in the same font size:
font-size: 2.5em
font-size:2.50em
font-size: 2.500em
