Question

ALL COMPONENTS ARE DISPLAYED OK. BUT WHEN I PRESS F12 AND HOVER OVER NAVBAR-LEFT, it’s height is that of 0px. I think I need to solve this by placing a small div with class clear somewhere, but I don’t know where exactly!

<div class="core-container">
    <div class="core-content">
        <div class="navbar">
            <div class="navbar-left">
                <div class="navbar-logo">
                    LOGO
                </div>
                <div class="navbar-suggestions">
                    SUGGESTIONS
                </div>
                <div class="navbar-notifications">
                    NOTIFICATIONS
                </div>
                <div class="clear">
                </div>
            </div>
            <div class="navbar-right">
                <ul>
                    <li>Profiles & Schedules</li>
                    <li>Settings</li>
                    <li>Log Out</li>
                </ul>
            </div>
            <div class="clear">
            </div>
        </div>
    </div>
</div>

css code:

/MASTER PAGE/

.core-container
{
    margin-top: 100px;
    border: 1px solid black;

}

.core-content
{
    width: 1000px;
    margin-left: auto;
    margin-right: auto;
    padding: 10px 20px 10px 20px;
}

.navbar
{
    border: 1px solid red;   
    padding: 10px 5px 10px 5px;
}

.navbar-right div
{
    float: right;
}


.navbar-left div
{
    border-right: 1px solid red;
    float: left;
    padding-right: 10px;
    margin-right: 10px;
}

.navbar-right ul li
{
    list-style-type: none;
    float: right;
    padding-left: 10px;
    margin-left: 10px;
    border-left: 1px solid red;
}
.clear
{
    clear: both;
}

Answer 1

Yes, everything in your navbar-left is floating, so its height remains 0. But is that a problem? It looks good on the screen!

Anyway, the quick answer is to append float:none to the style for the clear class. Make sure you make it specific enough to override the styles for .navbar-left div and navbar-right div though, like this:

.navbar-left .clear, .navbar-right .clear
{
    clear: both;
    float:none;
}
