## Headings

`H1`, `H2`, `H3`, `H4`, `H5` and `H6` are used for document headings. You always need the start and end tags. `H1` elements are more important than `H2` elements and so on, so that `H6` elements define the least important level of headings. More important headings are generally rendered in a larger font than less important ones. Use the optional `ALIGN` attribute to set the text alignment within a heading, e.g.

      <H1 ALIGN=CENTER> ... centered heading ... </H1>

The default is left alignment, but this can be overridden by an enclosing `DIV` or `CENTER` element.
