Footer width issue

Question

I'm having a little problem here. I have the following CSS code:

body
{
    margin: 0 0 200px; //Same height of the footer
}
div.content
{
    display: table;
    margin: 0 auto;
}
div.main-content
{
    margin: 20px 10px;
    text-align: left;
    background-color: rgba(255, 255, 255, 0.95);
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
    padding: 15px;
    -webkit-box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
    -moz-box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
    box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
}
footer
{
    position: absolute;
    left: 0;
    bottom: 0;
    height: 200px;
    width: 100%;
    overflow: auto;
    background-color: rgba(67, 191, 115, 0.95);
}

By this way, in all pages I use:

<div class='content'>
    <div class='main-content'>
        //Page content goes here
    </div>
</div>
<footer>
    //Footer content goes here
</footer>

My problem is that the footer is not keeping the width of the page if the resolution is lower than the content, becoming like this:

I've created this fiddle that shows the problem too: http://jsfiddle.net/pmb1vbdh/1/
See how the footer don't expand with the table and lets a white space? How I can solve this? Thanks!

Answer 1

It works. Check this.

div.content
{
    display: table;
    margin: 0 auto;
}
div.main-content
{
    margin: 20px 10px;
    text-align: left;
    background-color: rgba(255, 255, 255, 0.95);
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
    padding: 15px;
    -webkit-box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
    -moz-box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
    box-shadow: 0px 4px 5px 0px rgba(0,0,0,0.75);
}
footer
{
    position: absolute;
    left: 0;
    bottom: 0;
    height: 200px;
    width: 100%;
    overflow: auto;
    background-color: rgba(67, 191, 115, 0.95);
}

<div class='content'>
    <div class='main-content'>
        //Page content goes here
    </div>
</div>
<footer>
    //Footer content goes here
</footer>
