Hi teeray, awesome, thanks a lot for the heads up on this and the screenshot. Yes, so it looks like it is caused by the css changes, could you try reverting them and see if all buttons then align normally?
Oh right, got it, that makes sense. If you update to the latest 5.0.3 version of DiggDigg, the Twitter button should be fixed. We are also working on having the Like button centered, which looks a little bit odd.
The one thing I am not quite sure is the G+ button, which is cut off here, I will look into this and see if we can align that as well. Thanks for clarifying! 🙂
