Subscripts and Superscripts
To display a superscript, enclose the text to be superscripted between <sup> and </sup> For example E=mc<sup>2</sup> displays E=mc2
Subscripts are similar, except that the tags <sub> and </sub> are used. For example H<sub>2</sub>O displays H2O
Preformatted Text
Sometimes (such as when typing equations) it is useful to have your spacing maintained, but html will normally decrease multiple spaces to a single space. To preserve your own spacing, enclose the text between <pre> and </pre>
