我正在为Wordpress制作一个自定义的子主题，我似乎无法获得100%的页脚宽度来表示。

实时示例页面：http://glustik.com/wordpress/

我尝试了多种方法，但我无法显示页脚背景，页脚的内容显示得很好。

Here is the Footer Code I am Using.（我正在尝试复制标头）

#footer{
    width: 100%;
    margin:20px 0 20px 0;
    height:280px;
    border: 1px solid;
    border-top-color:rgba(255, 255, 255, 0.14); 
    border-bottom-color:rgba(0, 0, 0, 0.14);
    border-left-color:rgba(0, 0, 0, 0.14);
    border-right-color:rgba(0, 0, 0, 0.14);
    display:block;
    -moz-box-shadow: 0 0 15px 10px rgba(0,0,0,0.4);
    -webkit-box-shadow: 0 0 15px 10px rgba(0,0,0,0.4);
    box-shadow: 0 0 15px 10px rgba(0,0,0,0.4);
    background: #262626; /* Old browsers */
    background: -moz-linear-gradient(top,  #262626 0%, #131313 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#262626), color-stop(100%,#131313)); /* Chrome,Safari4+ */

    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr=\'#262626\', endColorstr=\'#131313\',GradientType=0 ); /* IE6-9 */
}
