I'm currently working on a site that requires slideshows, and I'm using the bxSlider script. The way it works right now is the code finds a span id="next_1" and span id="prev_1' and inserts a <a href=''>+</a>. I've got it setup so the span elements are white boxes, and when hovered will go black. The only clickable element is the + inside the span. I'm wondering how to resize the <a> element to fit the entire span element.
In the CSS you can select the <a> tag and add display: block and padding: 8px and remove those properties from the .button class. Hope it helps you. Thanks.
