Question

How come the navigation buttons are not visible?

I'm using jQuery and owlcarousel (http://owlgraphic.com/owlcarousel/).

    <div class="item">
        <img src="http://placehold.it/50x50" alt="Owl Image" />
    </div>
</div>

js ..

$(document).ready(function () {
    $("#owl-demo").owlCarousel({

        autoPlay: 3000, //Set AutoPlay to 3 seconds
        dots: true,
        items: 2,
        itemsDesktop: [1199, 3],
        itemsDesktopSmall: [979, 3]
    });
});

css ..

#owl-demo .item {
    margin: 3px;
}
#owl-demo .item img {
    display: block;
    width: 50%;
    height: auto;
}

Answer 1

The minified css file you have doesn't appear to have a style for that element: .owl-theme .owl-controls .owl-page span.

Here are the styles that are applied by the demo on the owlgraphic.com site: http://jsfiddle.net/s10bgckL/2/
