我是否正确使用CSS父>子选择器？

<div id=\"footer\">
    <a href=\"/\">Home</a> | 
    <a href=\"/about\">About</a> | 
    <a href=\"/contact\">Contact</a>
</div>

#footer {
    position: relative;
    float: left;
    background: white;
    width: 960px;
    height: 50px;
    border-bottom-left-radius: 50px;
    border-bottom-right-radius: 50px;
    -moz-border-radius-bottomleft: 50px;
    -moz-border-radius-bottomright: 50px;
    box-shadow: 2px 2px 3px #000;
    -moz-box-shadow: 2px 2px 3px #000;
    -webkit-box-shadow: 2px 2px 3px #000;
}
#footer > a {
    padding-top: 10px;
}

#footer

<a>

parent > child
