[Plugin: Meteor Slides] Page nagivation width

I have 12 images in a slideshow and would like the page navigation to be in a single row below the images. Currently, after 8 images the navigation wraps into a second row. See dubhlinnpub.com/new-slider. Where in the css is this “width” controlled?

I have figured out I can move the slider navigation left and right by adjusting the css below. Is this the proper method to center the navigation under the images?

#meteor-buttons {
    margin-left: 200px;
    width: auto !important;
}
