removing 1px "frameborder" from the fracebook iFrame (app)

So, facebooks somehow adds a 1px border to your appplication when using an iFrame.

Is there any way to get remove this?

I checked the source code, and it has frameborder="0"

My .php also contains:

html, body, iframe, div {
     开发者_如何转开发   border: 0px;
        margin: 0px;
        padding: 0px;
        }

what to do?

(or do I just have to live with only having 748 px?)

I found out it was because I was using some old setting for embedding my app. This setting is no longer available, so this is of no use anymore!

anyway, the facebook frame code has a bug, it should use frameBorder="0" instead of frameborder (note the capital B, needed for it to work in ie7 and below)
