正在为这个而苦苦挣扎。一切似乎都很好，但我无法让内容在 <div id="contacts"> 中居中和 <div class="contacts2">部分。
我错过了一些东西，盯着它看的时间太长了，以至于没能找到它。希望这里有人能发现我的问题。
代码如下:

最佳答案
如果您删除 float: left 并将 display: inline-block 添加到 .admin_list, .admin_list_img , .pi_list, 和 .pi_list_img 它将居中。看起来您将不得不在管理部分中处理联系人的维度。
关于html - 不能在其他 div 标签中居中 div，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11001602/
