Okay, new topic.
Could it be that this code

Code:

ul#picture_legend li,ul#privmsgs-menu li {
    display: inline !important;
}

blocked this effect hover? This hover in CSS:

Code:

.rozsuwacz{letter-spacing: -2; transition: 2s;-moz-transition:
2s;-o-transition: 2s;-htm-transition: 2s;-webkit-transition: 2s; }
.rozsuwacz:hover{letter-spacing:3;
 transition: 2s;-moz-transition: 2s;-o-transition: 2s;-htm-transition:
2s;-webkit-transition: 2s;}

 Thanks for any help.

You can take out the code I added and check to see if your code works.
