提问by Alexander Graham
How do I use a SASS selector within a pseudo selector on a hover state? Wanting to write less code and clean this up.

Preferred method, not working:
首选方法，不起作用：
div {
a {
transition: all 0.25s ease-in-out;
&:after {
content: ">>";
left: 10px;
:hover & {
left: 10px;
}
}
}
}
As opposed to:
与之相反：
div {
a {
transition: all 0.25s ease-in-out;
&:after {
content: ">>";
left: 10px;
}
&:hover {
&:after {
left: 10px;
}
}
}
}

Use &:hover:after {}for targeting the afterpseudo-element of the element being hovered over.
使用&:hover:after {}了针对after该元件的伪元素上空盘旋。
&:after:hover {}would select the afterpseudo-element and used on hover it.
&:after:hover {}将选择after伪元素并用于悬停它。
