The "trick" to making compatible web sites is to do the following:
<font color="red" class="bosswords">Bosses Words</font>
Old web browsers won't recognize the "class" attribute, so they will display the font colour as "red". However, newer web browsers will recognize the "class" attribute, and will display the text according to whatever is set in the "bosswords" class.
So, you could start out with just using the font command. But later, if the boss says his words should be in huge blinking text with a background image and a border on it, positioned centred in the page, you just have to define the "bosswords" class in your stylesheet. The original "font" command will be overridden with the stylesheet.
