Combine :after with :hover
提问by Chris
I want to combine :afterwith :hoverin CSS (or any other pseudo selector). I basically have a list and the item with the selectedclass has an arrow shape applied using :after. I want the same to be true for objects that are being hovered over but cant quite get it to work. Heres the code
我想结合:after使用:hover的CSS（或任何其他伪选择器）。我基本上有一个列表，并且selected该类的项目具有使用:after. 我希望对于悬停在上方但无法使其正常工作的对象也是如此。这是代码
#alertlist
{
list-style:none;
width: 250px;
}
#alertlist li
{
padding: 5px 10px;
border-bottom: 1px solid #e9e9e9;
position:relative;
}
#alertlist li.selected, #alertlist li:hover
{
color: #f0f0f0;
background-color: #303030;
}
#alertlist li.selected:after
{
position:absolute;
top: 0;
right:-10px;
bottom:0;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid #303030;
content: "";
}
<ul id="alertlist">
<li>Alert 123</li>
<li class="selected">Alert 123</li>
<li>Alert 123</li>
</ul>

Just append :afterto your #alertlist li:hoverselector the same way you do with your #alertlist li.selectedselector:
只需:after以与#alertlist li:hover选择器相同的方式附加到您的选择#alertlist li.selected器：
#alertlist li.selected:after, #alertlist li:hover:after
{
position:absolute;
top: 0;
right:-10px;
bottom:0;
border-top: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid #303030;
content: "";
}

在 scss 中
&::after{
content: url(images/RelativeProjectsArr.png);
margin-left:30px;
}
&:hover{
background-color:$turkiz;
color:#e5e7ef;
&::after{
content: url(images/RelativeProjectsArrHover.png);
}
}
