Answer 1

#overlapthis {
    background-image:url("mymessage.gif");
    height:100px;
    left:50px; /* play around with this */
    position:absolute;
    top:90px; /* and play around with this */
    width:500px;
}

#thebigimage {
    background-image:url("bread_wine.jpg");
    height:548px;
    margin-left:auto;
    margin-right:auto;
    position:relative; /* and this has to be relative */
    width:731px;
}

Answer 2

尝试

#overlapthis {
    position: absolute;
    top: ??px;
    left: ??px;
    z-index: 1;
}

Answer 3

如你所知，图像已经重叠。您无法看到它，因为您没有为您的重叠div添加大小。试试这个：

#overlapthis {
    background-image: url(mymessage.gif);
    width: 500px;
    height: 100px;
}

然后添加边距（和位置：绝对）以将图像定位在所需位置。
