This is the example of the STYLE tag. I've redefined the ways the headings 1 to 6 will show with this style sheet :

<STYLE>
<!--
H1 {font-size: 29pt; color: red}
H2 {font-size: 24pt; color: green}
H3 {font-size: 19pt; color: blue}
H4 {font-size: 15pt; color: black}
H5 {font-size: 11pt; color: black}
H6 {font-size: 13pt; color: black}
-->
</STYLE>

Header size 1

Header size 2

Header size 3

Header size 4

Header size 5

Header size 6

Back to the STYLE tag.
