CSS screws up text input length

I wanted to make my site's text be all arial rather than the default. So, I put in CSS to do that.

<style type="text/css">
<!--
body { font-family: Arial, Helvetica, sans-serif; }
td { font-family: Arial, Helvetica, sans-serif; }
th { font-family: Arial, Helvetica, sans-serif; }
h1 { font-family: Arial, Helvetica, sans-serif; }
h2 { font-family: Arial, Helvetica, sans-serif; }
h3 { font-family: Arial, Helvetica, sans-serif; }
h4 { font-family: Arial, Helvetica, sans-serif; }
h5 { font-family: Arial, Helvetica, sans-serif; }
font { font-family: Arial, Helvetica, sans-serif; }

-->
</style>

Now, all my text inputs are HUGE in netscape! I've tried wrapping the inputs with <font size=-2> to no avail.

Any ideas on how to make netscape actually use the "size=" element while using CSS?
