Why don’t you add support for the other browsers too? Also, you’re using the old webkit gradient method. The new one is the same as the other browsers.
.button{
background-image: -webkit-gradient(linear, left bottom, left top, from(#655445), to(#4a3421)); /* Saf4+, Chrome */
background-image: -webkit-linear-gradient(bottom, #655445, #4a3421); /* Chrome 10+, Saf5.1+ */
background-image: -moz-linear-gradient(bottom, #655445, #4a3421); /* FF3.6 */
background-image: -ms-linear-gradient(bottom, #655445, #4a3421); /* IE10 */
background-image: -o-linear-gradient(bottom, #655445, #453819); /* Opera 11.10+ */
background-image: linear-gradient(bottom, #655445, #4a3421);} /* Currently not supported by any browser */
}
