First of all, thanks for this usefull plugin.
Could it be possible to add an alternate CSS in the release with a tick box allowing to switch between CSS2 and CSS3?
I ask this because actually the current CSS doesn't validate with W3C validator and returns the following errors:
.sociable-hovers Property opacity doesn't exist in CSS level 2.1 but exists in [css3] : 0.4 .sociable-hovers Property -moz-opacity doesn't exist : 0.4 .sociable-hovers Parse Error opacity=40) .sociable-hovers:hover Property opacity doesn't exist in CSS level 2.1 but exists in [css3] : 1 .sociable-hovers:hover Property -moz-opacity doesn't exist : 1 .sociable-hovers:hover Parse Error opacity=100)
I am aware that this property will work with almost, if not all, web browsers. However, it is still confusing for customers and/or visitors who click on the "Valid CSS" button at the bottom of my blog page!
