You are missing the length unit px
.
Use this in the css :
#container3.on {
-webkit-transform: translate3d(230px, 0, 0);
-moz-transform: translate3d(230px, 0, 0);
-o-transform: translate3d(230px, 0, 0);
-ms-transform: translate3d(230px, 0, 0);
transform: translate3d(230px, 0, 0);
} /* It moves if from the starting point, 20px left in this example */
