Código:

#logo{
  -moz-opacity:.6;-moz-transform:rotate(0deg) scale(0.9) skew(1deg) translate(0px);
  -moz-transition-duration:.8s;-o-transform:rotate(0deg) scale(0.9) skew(1deg) translate(0px);
  -o-transition-duration:.8s;-webkit-transform:rotate(0deg) scale(0.9) skew(1deg) translate(0px);
  -webkit-transition-duration:.8s;filter:alpha(opacity=40);opacity:.6;transition-duration:.5s}
#logo:hover{-moz-opacity:.6;-moz-transform:rotate(0deg) scale(1.0) skew(1deg) translate(0px);-moz-transition-duration:.5s;-o-transform:rotate(0deg) scale(1.0) skew(1deg) translate(0px);-o-transition-duration:1s;-webkit-transform:rotate(0deg) scale(1.0) skew(1deg) translate(0px);-webkit-transition-duration:1s;filter:alpha(opacity=40);opacity:1;transition-duration:1s}a.mainmenu{-moz-border-radius:3px!important;-webkit-border-radiuhttp://zzzz11.omgforum.net/groupss: 3px!important;background-image:-webkit-gradient(linear,leftbottom,lefttop,color-stop(0.06,#0C0C0C),color-stop(0.97,#161817));border:1px solid #3d413d;border-radius:3px;margin-right:-8px;padding:6px 17px 6px 6px;text-decoration:none}a.mainmenu:hover{background-image:-webkit-gradient(linear,leftbottom,lefttop,color-stop(0.08,#0C0C0C), color-stop(1,#1C1C1C) );border:1px solid #353535;color:#fff;text-shadow:none}
