day5 页面布局

1.主站

　　　　

        <div class='pg-header'>
            <div style='width:980px;margin:0 auto;'>
                内容自动居中
            </div>
        </div>


        <div class='pg-content'></div>


        <div class='pg-footer'></div>

 

 

2.后台管理布局

                   position：

                            fixed          --永远固定在窗口的某个位置

                            relative    --单独无意义

                            absolute  --第一次定位，可以在指定位置，滚轮滚动时，不在了
