Welcome to WebmasterWorld designer123. I'm only aware of one method of feeding a rule to Opera 7.x and over without affecting other browsers, and its usefulness will be limited to the extent that it depends on features not yet implemented in other browsers. Once those other browsers catch up, then the hack will become less and less useful.

The syntax is as follows:

@media all and (min-width: 0px){
p {
color:green;
}
}

A more detailed explanation can be found here [virtuelvis.com].

As Opera is one of the most standards-compliant browsers out there, it is almost always better to make the page work without hack in Opera and Firefox and save the hacks for IE6 etc. using conditional comments.
