我需要添加一个css样式类，只用于没有库存的“标签”产品。
原始代码示例：

<label class="radio-label sw-radio-variation sw-radio-variation-2" title="l" for="l_2">

我要的代码：

<label class="out-stock radio-label sw-radio-variation sw-radio-variation-2" title="l" for="l_2">

如你所见添加到CSS代码缺货
谢谢
编辑：我的product-variation.php是

}

正如你在第60行看到的，你会发现标签是否有任何代码来添加一个自定义的CSS到这些标签，创建变量？
