Zurb Foundation 4.3.0 Orbit not showing slides

Question

I'm using Foundation 4.3.0 for a project, and am trying to set up Orbit in the most basic way. The javascript and CSS seem to be loading correctly, the images are loading, all the extra elements are inserted, etc. But the main <ul> always has a height of 0px. Here's my HTML:

<div class="row">
    <section class="large-12 columns">
        <div class="slideshow-wrapper">
            <div class="preloader"></div>
            <ul data-orbit="">
                <li><img src="/media/cache/8a/ec/8aec9d6a99dea3db235f24712e8f3f88.jpg"></li>
                <li><img src="/media/cache/20/88/208812a64eee2e7e9b8efe4b5f73c990.jpg"></li>
            </ul>
        </div>
    </section>
</div>

Here's the HTML once foundation.orbit.js does its thing:

<div class="row">
    <section class="large-12 columns">
        <div class="slideshow-wrapper">
            <div class="preloader"></div>
            <div class="orbit-container orbit-stack-on-small">
                <ul data-orbit="" class="orbit-slides-container" style="margin-left: -100%; width: 400%; height: 0px;">
                    <li data-orbit-slide="" style="width: 25%;"><img src="/media/cache/20/88/208812a64eee2e7e9b8efe4b5f73c990.jpg"></li>
                    <li class="active" style="width: 25%;"><img src="/media/cache/8a/ec/8aec9d6a99dea3db235f24712e8f3f88.jpg"></li>
                    <li style="width: 25%;"><img src="/media/cache/20/88/208812a64eee2e7e9b8efe4b5f73c990.jpg"></li>
                    <li data-orbit-slide="" style="width: 25%;"><img src="/media/cache/8a/ec/8aec9d6a99dea3db235f24712e8f3f88.jpg"></li>
                </ul>

                <a href="#" class="orbit-prev">Prev <span></span></a>
                <a href="#" class="orbit-next">Next <span></span></a>

                <div class="orbit-slide-number">
                    <span>1</span> of <span>2</span>
                </div>

                <div class="orbit-timer">
                    <span></span>
                    <div class="orbit-progress" style="overflow: hidden; width: 54.15%;"></div>
                </div>
            </div>

            <ol class="orbit-bullets">
                <li data-orbit-slide-number="1" class="active"></li>
                <li data-orbit-slide-number="2" class=""></li>
            </ol>
        </div>
    </section>
</div>

I have tried to put explicit width + height on the images, put class="active" on one slide when generating the HTML, change various Foundation settings, etc, and nothing seems to work.

When I compare the HTML to the live example in the Foundation docs, I notice that in the working version, a z-index is always set dynamically on the slides. On my site, no z-index is ever set. And of course, the ul in the working version has an inline CSS height which equals the height of the slides.

If I manually set the ul height to 300px, everything looks right, except I see no images. If I set div.orbit-container to overflow: visible, I will see the edge of one of the slides to the left of the container.

Any ideas would be much appreciated.

Answer 1

I'm going to try to avoid being overly verbose here.. but this is what I've found and while I wouldn't call this a complete fix, because i'm not sure what started the differences in css the following code solved the problem.

I found this because I have a local environment as well as a dev environment for the site. The local environment was working great, but the production environment had all the issues you mentioned above.

The first issue of course is the generated container div setting the height to 0px. This is strange enough. I manually added the height to the container in the css. The reason all the images are hiding is they're set to margin-left: 100% or some large left margin and they're all positioned absolutely. I wish I could be more help as to why the code differences are present, maybe I'll find more time to investigate further but for now its working.

Anyway, the following was the fix:

.orbit-container { height:250px; }  

.orbit-container .orbit-slides-container > * {
  position: relative;
  margin-left: 0;
  float: left;
  height: 100%;
}

Answer 2

.orbit-container { height:auto; }  

.orbit-container .orbit-slides-container > * {
  position: relative;
  margin-left: 0;
  float: left;
  height: 100%;
}

A little upgrade from a previous solution. With this modification, it will be more easy to show the slideshow on a phone and a desktop.
