Can’t change the style of a submit input type? [closed]

The fault is from the following code, change the colors or remove it.

.xoouserultra-wrap a.xoouserultra-button:hover, input[type=submit].xoouserultra-button:hover, input[type=submit].xoouserultra-button:focus, input[type=button].xoouserultra-button:hover, input[type=button].xoouserultra-button:focus, .xoouserultra-wrap a.xoouserultra-button:active, input[type=submit].xoouserultra-button:active, input[type=submit].xoouserultra-button:active, input[type=button].xoouserultra-button:active, input[type=button].xoouserultra-button:active {
    border: 1px solid #1278b2;
    background-color: #1278b2;
    background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#1278b2), to(#1391da));
    background-image: -webkit-linear-gradient(top, #1278b2, #1391da);
    background-image: -moz-linear-gradient(top, #1278b2, #1391da);
    background-image: -ms-linear-gradient(top, #1278b2, #1391da);
    background-image: -o-linear-gradient(top, #1278b2, #1391da);
    box-shadow: inset 0 -1px 1px -1px #fff;
    color: #fff;
    padding: 4px 10px;
}

Hope it works, good luck.
