Minamaze, changing theme colors

I tried to change the colors of the buttons with custom css (see below as it appears in the source of the page), but it has no effect. The buttons are still red (#F33F3F). What can be the reason?

<style type=”text/css”>
body {
font-family: georgia,\”times new roman\”,times,serif;
font-size: 16px;
}
#pre-header {
background: #00529b;
}
#pre-header-search .search {
background-color: #FFFFFF;
}
.themebutton, button, html input[type=\”button\”], input[type=\”reset\”], input[type=\”submit\”] {
background: #232D84;
}
.themebutton:hover, button:hover, html input[type=\”button\”]:hover, input[type=\”reset\”]:hover, input[type=\”submit\”]:hover {
background: #3F4AA8;
}
.wpcf7-form input {
width: auto;
}
</style>

thanks in advance
