添加position:relative到#center,然后left:0px到#menu.
绝对定位的元素相对于其最接近的父母定位.最好给出你想要的项目左/右和上/下坐标,以防止你找到的奇怪结果.
您应指定顶部和左侧位置并添加position:relative到直接父级:
#center {
float: left;
width: 300px;
height: 500px;
background-color: green;
position:relative;
}
#menu {
width: 300px;
height: 45px;
background-color: pink;
position: absolute;
z-index: 1000;
top: 100px;
left: 0;
}
一个现实的例子:http://jsfiddle.net/ambiguous/vRJMd/
默认值left是auto,或多或少意味着浏览器可以做任何它认为合理的事情.此外,绝对定位的元素相对于最近的祖先定位,其位置不是static(可能<body>在您的情况下).
