當高度未知時，如何在垂直方向上對齊div的內容？

Question

這是我的構造：

如您所見，圖像的高度各不相同，但我希望它們都在中間。 怎么做？

如何使其更加簡單並與舊版瀏覽器兼容？

這是您可能要實現的目標的我的版本； 具有更少的代碼和更好的可見性（我希望）。 看到自己（全屏），它也很敏感！

Answer 2

您可以將其更改為flex布局，使用起來會容易得多。

添加display: flex到行（ .shoutbox_smileTableContainer ）。 然后，使單元格（ .shoutbox_smileTable ） display: flex並添加align-items: center以垂直對齊內容，然后justify-content: center以水平對齊。

 #SBSMILES { overflow-x: hidden; overflow-y: scroll; } .shoutbox_smileTable { width: 25%; padding-bottom: 100%; margin: 0 -1px -100% -1px; background-color: white; border: 1px solid black; display: flex; justify-content: center; align-items: center; } .shoutbox_smileTableContainer { display: flex; }

Answer 3

使用height: 100%且vertical-align: middle inline-block幫助器。 據我所知，這是最好的跨瀏覽器解決方案。
