通用兄弟选择器

兄弟选择符，位置无须紧邻，只须同层级，A~B 选择A元素之后所有同层级B元素。

former_element ~ target_element { style properties }

p ~ span {
  color: red;
}

上面的CSS作用于下面的HTML中:

<span>This is not red.</span>
<p>Here is a paragraph.</p>
<code>Here is some code.</code>
<span>And here is a span.</span>

则会产生下面的效果:

This is not red.

Here is a paragraph.

Here is some code.And here is a span.
