I've a proble with a simply CSS/HTML menu!
When I hover in the second voice of menu, the submenu opens over the main menu and not down!
Why?

The CSS code is here:

```
* {
    margin: 0;
    padding: 0;
}
#navbar {
    height: 70px;
}
.navbar > li, .navbar > li > a #navbar ul {
    position: absolute;
}
#navbar, #navbar ul {
    .background {
        color:orange;
    }
}
#navbar li {
    float: left;
    list-style: none;
    line-height: 25px;
    display: inline;
}
#navbar ul li {
    display: inline-block;
    float: none;
}
#navbar li ul {
    display: none;
}
#navbar li ul li {
    list-style:none;
    margin:0;
    padding:0;
}
#navbar a {
    color: black;
    display: block;
    font-size: 20px;
    padding: 0 10px;
    text-decoration: none;
    list-style: none;
    float: left;
}
#navbar li:hover > a {
    background: red;
}
#navbar a:visited {
    display: block;
    padding: 4px 16px;
    color: #fff;
    text-decoration: none;
}
#navbar a:focus #navbar a:hover #navbar a:active {
    background-color: #D76120;
    color: #FFFFFF;
    text-decoration: none;
}
#navbar li:hover ul {
    display: block;
    position: absolute;
    width:130px;
    padding: 0;
    margin: 0 0 0 -1px;
    border:1px solid #D76120;
    background: #2D4E6C;
    font-size:.8em;
}
#navbar li li {
    border-bottom:1px solid #D76120;
    width: 130px;
}
.fa {
    font-size: 40px;
    line-height: 70px;
}
.fa-bars {
    color: #3498db;
}

```

the HTML code is 

```
<div id="navbar">
    <ul>
        <li><a href="pagina1.html"><i class="fa fa-home"></i><div>Home</div></a></li>
        <li><a href="pagina1.html"><i class="fa fa-home"></i><div>ciao</div></a>
            <ul>
                <li><a href="#">Roma</a></li>
                <li><a href="#">Milano</a></li>
                <li><a href="#">Torino</a></li>
            </ul>
        </li>
        <li><a href="pagina4.html"><i class="fa fa-home"></i><div>ciao</div></a></li>
        <li><a href="pagina5.html"><i class="fa fa-home"></i><div>ciao</div></a></li>
    </ul>
</div>

```
