With 'inspect element' to check the css,I found multiple .menu with same version

Where do I see two .menu by ‘inspect element’ here?

Below is sample code.

.menu {
    background-color: #C53737;
    background-image: -moz-linear-gradient(center top , #585858, #3D3D3D);
    clear: both;
    margin: 0px auto;
}
.menu, .menu ul {
    min-height: 0px;
}
.menu, .menu ul {
    display: block;
    list-style-type: none;
    margin: 0px;
    padding: 0px;
}
.menu {
    background-color: #585858;
    background-image: -moz-linear-gradient(center top , #585858, #3D3D3D);
    clear: both;
    margin: 0px auto;
}
