I am trying to apply css to facebook like button. I know that it is violating TOS to change how the like button look. All I am trying to do is change the background of facebook like button to make it consistence with my website.
I googled about it and found several articles that I can style facebook like button if I am using fbml because fbml does not use iframe. The problem is, it looks like facebook is using iframe for fbml as well.
as far as I know, I can't directly style a webpage that is included in an iframe.
Is there an api for styling (in my case, changing background only!!) the like button?
You can use dark or light theme.
You can not do anything to an iframe of whom's src attribute is not your domain.
The only thing I can think of is an ugly hack using absolute positioning, opacity and z-index, but I don't think it is worth mentioning.
how about over riding the image with another? i know its not the best practice, but u can't change the Facebook branded "Like" button
