I am creating a website using Wordpress. To add a slideshow of images I used the <a href="http://wordpress.org/extend/plugins/slider3d-gallery/" rel="nofollow">slider 3d plugin</a>. I added the shortcode to one of my pages, but what is happening is that the slideshow appears only in a small portion of the page. I want it to appear by the header on at least half of the page. How can I achieve this?
