I am adding a Facebook Like button to the blog posts at work and so I looked for a WordPress plugin. The highest rated one I found is called Simple Facebook Like by a guy named Huseyin Berberoglu.
I had a bit of a problem getting the button to go where I wanted because the iframe that gets added to the page doesn’t have an ID or a class for me to address it by. I modified the source to stick in a class quickly and easily and dropped a comment on the guy’s blog to see if he would add it as an option for the plugin so future versions wouldn’t overwrite my change, and then I decided that I would just do it myself.
So I created a patch that can be applied to version 1.0.1 to let you specify a class for the iframe so you can use CSS to move it around more easily.
