CSS :: child设置为在父悬停时更改颜色，但是当悬停本身时也会更改颜色
问题描述：
我有一个代码，它具有< a>作为父级和< span>作为孩子内。我写了一些CSS，改变孩子的边框颜色时悬停在父母。
I am having a code that has the <a> as parent and <span> as child within . I have written some CSS which changes border color of the child when hovered over parent. It works when I hover over parent, but if I hover over child it also changes color and it shouldn't.
这里有一些代码：
HTML
<a class="parent">
Parent text
<span>
Child text
</span>
</a>
CSS
.parent{
padding:50px;
border: 1px solid black;
}
.parent span{
position:absolute;
top:200px;
padding:30px;
border: 10px solid green;
}
.parent:hover span{
border: 10px solid red;
}
