我目前正在开设一个呼叫中心统计页面，我真的刚开始参与HTML5 / CSS世界。我有一个小问题（对我很重要），过去两天一直困扰着我。在我的网页的左上角，我需要“100％”和“100”水平和垂直居中。我已经尝试了几个东西，比如显示：表格单元格，线条高度以及其他一些东西，但似乎没有任何东西似乎垂直和水平居中。

添加以下内容可达到您想要的效果：
#queuewrapper { display: table; }
#queuepercentage, #queueholding { display: table-row; }
#queuepercentage h1, #queueholding h1 { display: table-cell; height: 90px; vertical-align: middle; text-align: center; }
