For all sliders to be one size, enter the following into css:
.wikiaPhotoGallery-slider-body { width: 700px; }
For multiple slider widths, classes need to be defined in css:
<div class="large-slider"> <gallery type="slider"></gallery> </div> <div class="small-slider"> <gallery type="slider"></gallery> </div> then you'd use this CSS... .large-slider .wikiaPhotoGallery-slider-body { width: 700px; } .small-slider .wikiaPhotoGallery-slider-body { width: 400px; }
