An element's leading is the distance between the baselines of two text lines. Note that the spacing is added before each line, not after. This setting doesn't work well on text lines that use multiple font sizes on the same line of text. You can set this property to any of the values shown in Table B.14. Text is right justified.
Text is centered within the element.
Table B.15 describes the values you can assign to this property. You can combine these values, too. You can set this property to any valid length. You use the vertical-align property to change the vertical position of the element's text within the element itself. You can use one of the keywords described in Table B.17.
