The website: <http://speelgoedwinkelxl.nl/>

I can't get the bottom div aligned in the center

It is the part witch says Meld je aan voor onze nieuwsbrief

I tried to use margin: 0 auto; and text-align: center; but both doesn't work.

The code is from a Magento template but I can't find out why I cant get it centered.

```
<div class="ma-footer-static-container-bottom1">
        <div class="ma-footer-static">
            <div class="row-fluid show-grid">
                <div class="social span4">
<div><div class="footer-subscribe">
    <div class="block-title">
        <strong><span>Meld je aan voor onze nieuwsbrief</span></strong>
    </div>
    <form action="http://speelgoedwinkelxl.nl/newsletter/subscriber/new/" method="post" id="newsletter-validate-detail">
        <div class="newsletter-content">
            <div class="form-subscribe-header">
                <!--<label for="newsletter"></label>-->
            </div>
            <div class="input-box">
               <input type="text" name="email" id="newsletter" title="Meld je aan voor onze nieuwsbrief" class="input-text required-entry validate-email">
            </div>
            <div class="actions">
                <button type="submit" title="Inschrijven" class="button"><span><span></span></span></button>
            </div>
        </div>
    </form>
    <script type="text/javascript">
    //<![CDATA[
        var newsletterSubscriberFormDetail = new VarienForm('newsletter-validate-detail');
    //]]>
    </script>
</div>
</div>
</div>            </div>
        </div>
    </div>

```
