Hi Petteri

This is the required code for those buttons, please copy it to your custom CSS and make any changes you need

.post-navigation a:hover, #image-navigation a:hover {
    background: #ffffff;
    background: -webkit-gradient(linear, left bottom, left top, color-stop(0, #ebebeb), color-stop(1, #ffffff));
    background: -ms-linear-gradient(bottom, #ebebeb, #ffffff);
    background: -moz-linear-gradient(center bottom, #ebebeb 0%, #ffffff 100%);
    background: -o-linear-gradient(#ffffff, #ebebeb);
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#ebebeb', GradientType=0);
}

.post-navigation a, #image-navigation a {
    background: #ffffff;
    background: -webkit-gradient(linear, left bottom, left top, color-stop(0, #dfdfdf), color-stop(1, #ffffff));
    background: -ms-linear-gradient(bottom, #dfdfdf, #ffffff);
    background: -moz-linear-gradient(center bottom, #dfdfdf 0%, #ffffff 100%);
    background: -o-linear-gradient(#ffffff, #dfdfdf);
