How to edit module position size to insert a slide

Hello, i still can not figure how to insert a jfslide show on top of my page and make it a little bigger in size then the template def. size. I need to have the slide bigger then the rest of the page ( see pix)
Thank You

Something like this to be put at bottom of template_css.css:


.logo_pad,.search_box{
width:65%!important;
}

.logo_pad{
margin-left:-15%!important;
}
