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不居中?
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="https://source.unsplash.com/random/300*300?technology" alt="Dummy 1" /></li> <li><img src="https://source.unsplash.com/random/301*301?technology" alt="Dummy 2" /></li> </ul> </div> </body>
如果您设置了宽度,您可以使用:
position: absolute; margin-left: auto; margin-right: auto; left: 0; right: 0; text-align: center;
