我需要删除＆＃34; left＆＃34; bootstrap popovers的价值。我该怎么做？
我不需要在CSS中添加边距或更改左边的值，但只删除它（请检查元素以查看它，它当然是由bootstrap.js或tooltip.js添加的） 。
popover示例：http://jsfiddle.net/KyleMit/VUZhL/
以下代码属于bootstrap.js，它与工具提示/弹出窗口有关。

答案 0 :(得分：0)
Actually I recommend you do this in CSS.
.popover {
left: auto !important;
}
If you change base codes of bootstrap or tooltip.js with any update you have to remove it again and again.
