是否可以在悬停时更改选择列表选项的默认背景颜色？

HTML:

<select id="select">
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
</select>

select {
    -webkit-border-radius:25px; -moz-border-radius:25px; border-radius:25px;
}

select:hover {    
    background-color:gren;
}

option:hover {
    background-color:yellow;
}

option {
    -webkit-border-radius:25px; -moz-border-radius:25px; border-radius:25px;
    color:blue;
    background-color:yellow;
}

我尝试过选项:hover{background-color:red;},但没用.有人知道怎么做这个吗？

    string uname = (string) Session["fname"].ToString() + " " + Session["lname"].ToString(); //Session["fname"].ToString()+" "+Session["lname"].ToString();

    // Response.Write(uname);
