Show/Hide div on image click not working

Question

If you go to http://oandg.co.uk.s156312.gridserver.com/#work and select a portfolio item and click 'More' you will see an image and a text box with a little 'i' in the corner.

I would like to make it so if you clicked the little 'i' the text box would disappear and if you clicked it again it would show.

I tried this but it does nothing:

$(function() {
$(".openBoxButton").click(function() {
      $('#colorbox').fadeIn(1200);
       $.colorbox(); 
         $('.rsABlock img.info').click(function(e) {
          e.preventDefault();
          $('.caption-background').toggleClass('hidden');
       });
  });
});

HTML:

<!-- Slide One -->
<div id="simple-slider-one" class="royalSlider rsDefault" style="width: 100%;">
    <a class="rsImg" href="images/Froosh/froosh1.jpg">  
        <div class="rsABlock">
            <img src="images/info.svg" alt="" class="info">
            <div class="caption-background">
                <h4>What we did for them</h4>
                <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quidem distinctio deserunt nostrum illum dolor obcaecati eaque ipsam! Distinctio, ipsa accusamus saepe temporibus ex pariatur possimus quidem sapiente obcaecati labore iusto.</p>
        </div>
        </div>
    </a>
    <a class="rsImg" href="images/Froosh/froosh2.jpg">  
        <div class="rsABlock">
            <img src="images/info.svg" alt="" class="info">
            <div class="caption-background">
                <h4>What we did for them</h4>
                <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quidem distinctio deserunt nostrum illum dolor obcaecati eaque ipsam! Distinctio, ipsa accusamus saepe temporibus ex pariatur possimus quidem sapiente obcaecati labore iusto.</p>
        </div>
        </div>
    </a>

Any ideas?

$(function () {
    $(".openBoxButton").click(function () {
        $('#colorbox').fadeIn(1200);
        $.colorbox();
    });

    $('.rsABlock').on('click', 'img.info', function (e) {
        e.preventDefault();
        $('.caption-background').toggleClass('hidden');
    });
});

EDIT: Just to add some explanation of this, you were previously adding a click handler on every click of the ".openBoxButton" class - now I did NOT search for that class in your page but placing this outside that function prevents the event hanlder from being repeatedly added.

EDIT based on comment: I tested using developer tools and it works. #colorBox does not seem to work - likely added/removed cycle or something.

 $(document).on('click', 'img.info', function (e) {
    e.preventDefault();
    $('.caption-background').toggleClass('hidden');
});

Yes... You can do that with CSS:

<!-- HTML -->
<div class="container">
    <img src="http://placekitten.com/285/275" class="portfolio" alt="">
    <div class="mask">
         <h2>Froosh</h2>
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quidem nostrum     porro iste excepturi vel ducimus cumque minima rem voluptates cum!</p>
    </div>
</div>

/* CSS */
.container {
    /* Some width */
    width: 200px;
    display: inline-block;
    position: relative;
    border: 3px solid #ccc;
}
.container img {
    display: block;
    width: 100%;
}
.container .mask {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    /* some color */
    background: rgba(255, 255, 255, 0.5);
    opacity: 0;
    -webkit-transition: all 0.3s ease-out;
    /* Chrome 1-25, Safari 3.2+ */
    -moz-transition: all 0.3s ease-out;
    /* Firefox 4-15 */
    -o-transition: all 0.3s ease-out;
    /* Opera 10.50–12.00 */
    transition: all 0.3s ease-out;
    /* Chrome 26, Firefox 16+, IE 10+, Opera 12.10+ */
}
.container:hover .mask {
    opacity: 1;
}

Is up to you put some style on the .mask element
