我在将属性position设置为的元素居中时遇到问题absolute。有谁知道为什么图像没有居中?
position
absolute
body { text-align: center; } #slideshowWrapper { margin-top: 50px; text-align: center; } ul#slideshow { list-style: none; position: relative; margin: auto; } ul#slideshow li { position: absolute; } ul#slideshow li img { border: 1px solid #ccc; padding: 4px; height: 450px; }
<body> <div id="slideshowWrapper"> <ul id="slideshow"> <li><img src="img/dummy1.JPG" alt="Dummy 1" /></li> <li><img src="img/piano_unlicened.JPG" alt="Dummy 2" /></li> </ul> </div> </body>
如果设置了宽度,则可以使用:
position: absolute; margin-left: auto; margin-right: auto; left: 0; right: 0; text-align: center;
