:after，:before Internet Explorer 11中的问题 [英] :after, :before issues in internet explorer 11

问题描述

在我的网站设计中，我使用的是:before和:after伪元素.这些在Google chrome和firefox中运行良好.但是在使用Internet Explorer时遇到了麻烦.

In my website design, I am using :before and :after pseudo elements. These are working good in Google chrome and firefox. But having trouble with internet explorer.

我正在使用的代码是

#nav ul li.active:after {
  border-left: 20px solid transparent;
  border-right: 20px solid transparent;
  content: "";
  border-top: 13px solid rgba(2,155,223,0.9);
  position: absolute;
  bottom: -13px;
  width: 0px;
  margin-left: -20px;
}

出局权证是

1.在Google Chrome浏览器中

1.In google chrome

2.在Internet Explorer 11中

2.In internet explorer 11

IE是否阻止了此CSS?因为所有在:: before中具有的样式在IE11中均已删除.

is IE preventing this css? because all the styles with in ::before are shown as striked out in IE11.

推荐答案

在包括IE11在内的所有浏览器中，您都需要稍微修改一下CSS才能使下拉箭头对齐.请使用此CSS.

You have to modified your CSS a little bit to align the drop arrow in all browsers including IE11. Please use this CSS.

#nav li{
  display: inline-block;
  position: relative; /*Added Line*/
}

#nav ul li.active:after {
border-left: 20px solid transparent;
border-right: 20px solid transparent;
content: "";
border-top: 13px solid rgba(2,155,223,0.9);
position: absolute;
bottom: -10px; /*change from -13 to 10px*/
width: 0px;
/*margin-left: -20px;*/  /*REmoved Line*/
  left: 20px;/*Added Line*/
}
