IE8中手風琴菜單不起作用

Question

我可以在帶有引導主題的wordpress中工作，並使用bootstrap.boot的手風琴菜單在所有其他瀏覽器中都能正常工作，但在IE 8中無法正常工作，並且所有數據都被一個菜單與另一個菜單重疊。

這是acccordion菜單的代碼：

這是引導程序中用於手風琴的CSS：

.accordion {
  margin-bottom: 20px;
}
.accordion-group {
  margin-bottom: 2px;
  /*border: 1px solid #e5e5e5;
  -webkit-border-radius: 4px;
  -moz-border-radius: 4px;
  border-radius: 4px;*/
}
.accordion-heading {
  border-bottom: 0;
  background-color:#cccccc;
}
.accordion-heading .accordion-toggle {
  display: block;
  padding: 2px 4px;
  text-decoration:none;
  /*background-color:#e52b27;*/
}
.accordion-toggle {
  cursor: pointer;
  color:#5e5e5e;
  text-decoration:none;
}
.accordion-inner {
  padding: 2px 4px;
  border-top: 1px solid #e5e5e5;
  text-decoration:none;
}

Answer 1

手風琴有一個已知的IE錯誤： https ： //github.com/twitter/bootstrap/issues/4745

您需要將Bootstrap更新到最新版本。
