Bootstrap 3.2在文本旁邊垂直對齊圖像而不知道高度

Question

我正在使用bootstrap 3.2，並嘗試使用CSS在div內的某些文本旁邊的div中垂直對齊圖像。 該圖像具有img-response CSS類，因此其高度可以隨文本高度的變化而變化（因為文本的長度不同）。

我整理了一個快速示例http://www.bootply.com/MjLj4d5HET

我還沒有找到可以100％運作的解決方案，而且周圍環境很好。 我試過了

display: table-cell;
vertical-align: middle;
float:none;

但隨后又弄亂了使用push和pull CSS類的div的對齊方式。

任何幫助將非常感激！

Answer 1

除非您指定高度，否則div，部分，圖形，跨度等將占用其內容的高度。 因此，包含圖像的div是圖像的高度。 如果兩列的高度不相等，則不能將其放在該列旁邊的垂直中間。 我會使用jQuery。 CSS無法在IE8中正常工作。
