Image Hover on Twitter Bootstrap

Question

my name is Enrique and I'm having a problem with the :hover property on Twitter Bootstrap.

I made a rating system with 5 stars, but when a star is "hovered", the stars start to blink, a really mess

When I use the same system without any script, it works fine, that's why I think the problem are on Bootstrap or Jquery.

Here's my site beeing developed: http://apostilaz.pilha.inf.br/detalhaapostila

The stars are above the big green button writed (BAIXAR APOSTILA), when they are empty its hard to see, I know.

Here is a jsfiddle with the same code without any JS and the code below:

    padding: 0;
    list-style: none;
    clear: both;
    position: relative;
    background: url(../img/estrelas.png) no-repeat 0 0;
}

.semestrela {
background-position: 0 0;

After inspect your page a little i found you have no problems with the Scripts, your problem is with one of the css files. This one:

<link rel="stylesheet" type="text/css" href="http://apostilaz.pilha.inf.br/public/plugins/ui/css/flat-ui.css" media="all">

That flat-ui.css is adding an special CSS for the a tags:

a {
 color: #16a085;
 text-decoration: none;
 -webkit-transition: 0.25s;
 -moz-transition: 0.25s;
 -o-transition: 0.25s;
 transition: 0.25s;
 -webkit-backface-visibility: hidden;
}

To make your :hover stars work you need to delete the transition property, this is the cause for that behavior you can't go between stars without select the other one.

PD: Tested on your page with the google chrome inspector
