I'm trying to force a vertical scrollbar on a website. But when I put:

overflow: scroll;

in my css document, it does well is Safari and FF, but shows two scrollbars in IE7. How do I write a conditional in my linked css document (not in the html page itself) that will "overflow: auto;" when the browser is IE?

Thanks guys and girls.

It depends which version of IE you're targeting. Neither of these methods are official, they just rely on browser bugs that were planted by accident. Imagine that.
CSS

*overflow: auto; /*targets IE7 and below, with a star before it*/
_overflow: hidden; /*targets IE6 and below, with an underscore before it*/

Of course, there is no reason you can't just do conditional comments in the HTML and have a separate CSS file for each set of browsers. That is the only officially sanctioned way of operating.

Hey wayfarer07 - thanks for the info. I did it the html way and it works beautifully. I just created an IE only css document and linked to it last in my css links. Seems to work perfectly. I really appreciate the info.
