我目前正在使用列表的左侧菜单。一切正常,但现在我想对字体失真执行操作,在这种情况下,我试图将fa-caret-right移至fa-caret-down。列表未打开时,按fa-caret-right键,列表打开时,按fa-caret-down键。我的问题是如何通过CSS或JQuery来采用这种方法。我在寻找解决方案,但没有解决。这是我的js小提琴工作链接代码
https://fiddle.jshell.net/gLjbyjtm/4/
更新:1插入符号错误已解决Js拨弄新版本
在此版本中,我可以通过单击具有fa-angle-right的复选框标签来成功地将左侧菜单切换到左侧。问题在于fa-angle-right,它在切换时不会随左侧菜单一起移至左侧,或者当其宽度受到挤压时,跨度中的元素也应向左移动。以下是我从事js小提琴的工作。有什么建议么 ?

最佳答案
调整pseudo-element
/* Additional */
.nav-side-menu ul li:not(.collapsed) .arrow:before {
content: "\f0d7";
}
说明:
由于每当未打开手风琴项目时都会添加
.collapsed
类,因此我们可以将其用作目标选择器。而且由于没有打开手风琴项目时将其定位为目标的类,我们可以通过使用
:not()
-否定的pseudo-class选择器来实现。在这种情况下,它将选择不具有类.collapsed
的列表项元素-表示它们已打开。:not()
CSS伪类表示与选择器列表。因为它可以防止特定项目
选择,它被称为否定伪类。
例
/* Selects any element that is NOT a paragraph */
:not(p) {
color: blue;
}
