javascript - Div 中的垂直/水平对齐

Question

我目前正在开发一个调用中心统计页面，并且在 HTML5/CSS 领域才刚刚起步。我有一个小(对我来说很大)的问题，过去两天一直困扰着我。在我网页的左上角，我需要将“100%”和“100”水平和垂直居中。我已经尝试了几种方法，例如显示:表格单元格、行高和其他几种方法，但似乎没有什么能使我的文本垂直和水平居中。

如前所述，我对此很陌生，因此随时欢迎任何进一步的建议。

Answer 1

添加以下内容可实现您想要的结果:

#queuewrapper { display: table; }
#queuepercentage, #queueholding { display: table-row; }
#queuepercentage h1, #queueholding h1 { display: table-cell; height: 90px; vertical-align: middle; text-align: center; }
