css and mac's

[sle2002]

I created a website using css to tell what my font and attributes are. It doesn't seem to be working on my mac. I know that i am calling for Arial first in my font family and Mac's don't use that, but the next one is helvetica. And the font that is displaying looks more like times.

Here is my code from my css page.

Any thoughts?

<style type="text/css">
<!--
a {color: #B4290E; text-decoration: underline;}
a:link {color: #FB4290E; text-decoration: underline;}
}
.para {font-size: 11px; font-family: arial,helvetica,sans-serif; line-height: 16px; color: #000000; padding: 5px 7px 5px 5px;}
.para_header {font-size: 14px; font-family: arial,helvetica,sans-serif; line-height: 16px; color: #000000;}
.para2 {font-size: 11px; font-family: arial,helvetica,sans-serif; line-height: 16px; color: #000000; padding: 5px 5px 5px 0px;}

-->
</style>
