Incorrect column mappings on mobile

I have a four column column that collapses into two columns on tablets and one column on mobile.

The metadata and view style sheets look like this:

<link rel="stylesheet" href="style/main.css" type="text/css" media="screen">
<link rel="stylesheet" href="style/tablet.css" type="text/css" media="screen and (max-width: 960px)">
<link rel="stylesheet" href="style/mobile.css" type="text/css" media="screen and (max-width: 640px)">

<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=0, width=device-width">

Responsiveness works great when resizing the screen on the desktop, as shown here:

However, on mobile, the footer columns appear as two columns rather than one:

Here is the css from main.css

:

div#footer div.wrapper div.column {
    float: none !important;
    display: table-cell;
    width:25%;
    box-sizing:border-box;
    padding: 0 10px;
    border-right: 1px solid rgba(255,255,255,0.1);
}

Here is the css from tablet.css

:

div#footer { padding: 10px; }

div#footer div.wrapper div.column { width:50%; margin-bottom: 20px; border: none; float: left !important; }
div#footer div.wrapper div.column:nth-child(3) {
    clear:both;
}

... and here is the css from mobile.css

:

div#footer { padding: 10px; }
    div.column {
        width:100% !important;
        float:none !important;
    }

And finally the HTML (with placeholder text):

<div id="footer">
    <div class="wrapper">
        <div class="column">
            <h4>Important Links</h4>
            <ul>
                <li><a href="/">Homepage</a></li>
                <li><a href="/privacy">Privacy Policy</a></li>
                <li><a href="/terms">Terms of Use</a></li>
                <li><a href="/contact">Contact Us</a></li>
            </ul>
        </div>
        <div class="column">
            <h4>Important Links</h4>
            <ul>
                <li><a href="/">Homepage</a></li>
                <li><a href="/privacy">Privacy Policy</a></li>
                <li><a href="/terms">Terms of Use</a></li>
                <li><a href="/contact">Contact Us</a></li>
            </ul>
        </div>
        <div class="column">
            <h4>Important Links</h4>
            <ul>
                <li><a href="/">Homepage</a></li>
                <li><a href="/privacy">Privacy Policy</a></li>
                <li><a href="/terms">Terms of Use</a></li>
                <li><a href="/contact">Contact Us</a></li>
            </ul>           
        </div>
        <div class="column" style="border-right: none;" >           
            <h4>Header</h4>
            <p>Lorem ipsum dolor sit amet</p>
        </div>
        <div style="clear:both;"></div>
    </div>
</div>

How can I ensure that mobile devices display formatting mobile.css

as it does when simulating a mobile device in your desktop browser?

Refresh . The following, updated mobile.css

css code still results in two columns:

div.column {
    width:100% !important;
    float:none !important;
    clear: both !important;
    display: block !important;
}

I've had strange problems with display: table-cell;

before. For mobile css try repeating tablet styles anddisplay: block; 



div#footer { padding: 10px; }
div#footer div.wrapper div.column:nth-child(3) {
    width:100% !important;
    float:none !important;
    clear: both;
    display: block;
}

Add this to mobile.css

div#footer div.wrapper div.column {
    display: block;
}


When you use display: table-cell it calls the <div> to act like the <td> elements

remove you float:none !Important

and it will work

try this for mobile CSS.

div#footer { padding: 10px; }
div#footer div.wrapper div.column {
        width:100% !important;
    }

enter image description here
