我有这段代码，它使每个段落的类都不同于“ cl2”红色。
<head>
<style type="text/css">
p{ color:#000000; }
:not(.cl2){ color:#ff0000; }
</style>
</head>
<body>
<p class="cl1">This is a paragraph.</p>
<p class="cl2">This is second paragraph.</p>
<p class="cl2">This is third paragraph.</p>
<p class="cl3">This is fourth paragraph.</p>
<p class="cl2">This is fifth paragraph.</p>
<p class="cl2">This is sixth paragraph.</p>
<p class="cl4">This is seventh paragraph.</p>
<p class="cl5">This is eigth paragraph.</p>
<p class="cl1">This is nineth paragraph.</p>
</body>
如何扩展我的:not选择器以忽略例如类“ cl2”和“ cl4”？我试过了：:not(.cl2, .cl4){ color:#ff0000; }但它不起作用。
