css - 调整浏览器窗口大小时保持背景图像居中

Question

因此，我正在为 SMF 论坛进行布局，并且当浏览器窗口足够宽时，背景图像会完美居中。但是，当我开始缩小浏览器窗口时，背景图像开始向左移动。这是我当前的背景 CSS:

body
{
    background: #fefff1 url(../images/img/bg.gif) no-repeat;
    background-position:top center;
    margin: 0 auto; 
    color: #7C3C4A;
    padding: 0px 5%;
    font: 78%/130% "Verdana", "Arial", "Helvetica", sans-serif;
}

这是论坛的屏幕截图，以便您可以更好地对其进行可视化:
