Think you mean the drop shadow on them? 

Broadly it is:

.wrapper-shadow {
    box-shadow: none;
}

You can make it widget or page specific by adding 

#doc-page-enumber] or #doc-widget-tnumber] in front of the .wrapper-shadow above.

I know you have this triggered on a profile on Fark.Tools too, that is my preferred method :)

@Bfarkas this is what I was talking about in our message
