jQuery slideUp / slideDown not animating

I'm trying to create two div's with a header and a content, and when I click the header, the content is supposed to slide up to hide itself.

You can find my code on JSFiddle.

My HTML :

<div id="left-content">
    <div class="news-block">
        <div class="block-head">News membres</div>
        <div class="block-content"></div>
    </div>
    <div class="news-block">
        <div class="block-head">News premium & VIP</div>
        <div class="block-content"></div>
    </div>
</div>

And my JavaScript :

jQuery(document).ready(function($){
    $('div.news-block').on('click', '.block-head', function(){
        var content = $(this).parent().find('div.block-content');
        if (content.is(':visible'))
            content.slideUp("slow");
        else
            content.slideDown("slow");
    });
});

I red some posts saying that you can't use slideUp() on tbody for exemple, or on a floating div, but as you can see, my "content" div is not floating, and that's why I don't get why it's not working.

Do you have any idea ?

Thanks.

#left-content .news-block .block-content {
    background: #c3c3c3;
    margin-left: 8px;
    height: 50px; 
}

Use height instead of min-height css property.
