I think you are missing the point...

There was a discussion @area51 where i asked if the mini-buttons would be changed to css too. nickvergessen replied that that would be the case BUT the difficulty was the small font size.

So i did a local css test which came out nicely and i added some screenshots to the thread showing the result. I then asked that, if anyone would be interested i could give them the code. The reply was to put it on github so it could be reviewed....

...and that is what i did. You assume that css needs to be of version 2.1, but where does it say so? 

You are commenting on code that is being deleted (because it is outdated), you create an example that is really nice but at the same time doesn't even closely match the prosilver theme etc.etc.

Long story short, we are discussing the possibility of css-ing the mini-buttons and we are reviewing testcode i made just to see if the problems with the small font cabn be solved... that's all....
