无法更改HTML时如何使用CSS编辑特定的HTML文本？

Question

我想将“ Taxi Squad”的所有实例替换为“ Day Care”，并且因为我没有访问HTML的权限，但是可以上传自定义CSS，所以我想尝试通过CSS进行编辑，这样看起来像“日托”这样的方式适用于所有用户。我在这里遵循了一些答案，但是似乎无法“定位”我想要的文本（找不到正确的类？）。

这是HTML的摘要，其中显示了“出租车小队”。

.oddtablerow span{
 display:none;
}

.oddtablerow:after{
 content: "Day Care";   
}

我在做什么错，我该怎么做呢？我还能解释些什么细节以帮助了解情况？

非常感谢！

干杯！
