Event price transition updated

I was taking a look at the events and I noticed that the price transition on hover were too sluggish, so I thought that it would be better to change the CSS to use transform translateX rather than to transition the right property on hover.
I tested and noticed that it got much faster in Chrome, but had almost no difference in FF and IE.
