How to Center Masonry Container

Question

I'm trying to center a masonry container on a page. At the moment, it's aligned to the left. I have margin auto in my CSS and isFitWidth: true in JS, but neither seems to be doing anything. I've also tried putting display:block in my CSS.

This is the HTML;

<div id="masonry_container" class="group">

<div class="masonry_item">
    <a href="http://storyville.jonmarkoff.com/storyvillewp"target="_blank">
    <img src="images/storyville_home.png" alt="Storyville Entertainment"/>
    <h3>Storyville Entertainment</h3></a>
</div><!--masonry_item-->


<div class="masonry_item">
    <a href="http://www.ducklingfarm.com"target="_blank">
    <img src="images/udof_home.jpg" alt="Ugly Duckling Organic Farm"/>
    <h3>Ugly Duckling Organic Farm</h3></a>
</div> <!--masonry_item-->


<div class="masonry_item">
    <a href="http://www.underdonk.com"target="_blank">
    <img src="images/underdonk_home.png" alt="underdonk"/>
    <h3>Underdonk</h3></a>
</div> <!--masonry_item-->

<div class="masonry_item">
    <a href="http://www.jaeeunlee.com" target="_blank">
    <img src="images/jaeeunlee_home.png" alt="jaeeunlee"/>
    <h3>www.jaeeunlee.com</h3></a>
</div> <!--masonry_item-->

<div class="masonry_item">
    <img src="images/goindoor_hospitals.png" alt="goindoor"/>
    <h3>Goindoor</h3>
</div> <!--masonry_item-->

<div class="masonry_item">
    <img src="images/cakes_home.jpg" alt="wonderfully whimsical cakes"/>
    <h3>Wonderfully Whimsical Cakes</h3>
</div> <!--masonry_item-->

</div><!--#masonry_container .group-->

CSS;

.group {
    display: inline-block;
    clear:both;
}

.group:after {
    visibility: hidden;
    display: block;
    font-size: 0;
    content: " ";
    clear: both;
    height: 0;
}

#masonry_container {
margin:50px auto;
width:100%;
position:relative;
z-index:2001;
}

.masonry_item {
width:300px;
margin:0 0 20px 0px;
padding:20px;
}

.masonry_item:hover{ 
outline:1px solid white;
}

#masonry_container img {
width:100%;
}

and JS;

var container = document.querySelector('#masonry_container');
var msnry = new Masonry( container, {
    // options
    isFitWidth: true,
    itemSelector: '.masonry_item'
});

I'd appreciate your help!

I was trying to figure this out for myself today and thought I'd share a possible solution.

As per Masonry's own options page "isFitWidth": true seems to be the key

Here's their codepen example..

Here's my simplified and bare bones method..

html

<div class="masonry-container js-masonry"  data-masonry-options='{ "isFitWidth": true }'>
    <div class="image-div">
        <img class="image" src="" style="width: 200px; height: 100px;">
    </div>
    <!-- ..lots more divs in jsfiddle.. -->
</div>

css

.masonry-container {
    margin: 0 auto; /* this is the css that keeps the container centered in page */
}

.image-div {
    float: left;
    width: 230px;
    margin: 5px;
    font-size: 0;
}

.image {
    width: 230px;
    height: auto;
}
