Well, the Ever After theme was designed to have one column and footer widgets. You can't add widgets using CSS, but you can move things around on a page once they have been added. So, in this case, you can move the footer widgets up and to the right. To make it work, we'll need to use absolute positioning. That means you overlay, or position, the widgets where you want them on the page—and so if you change the height of anything in the header, keep in mind you may also need to adjust this type of custom CSS. Here is an example for you to play around with:
#primary {
width: 70%;
}
#supplementary {
width: 23%;
position: absolute;
top: 460px;
right: 0;
}
#supplementary.two .widget-area,
#supplementary.four .widget-area {
width: 100%;
}
