Answer 2

尝试#box h1 {“您的样式”}或#box #truth h1 {“您的样式”}

Answer 3

The problem is with the character encoding of your source code, not sure how you wrote it but copying into notepad and re-typing the line "color:#445668;" 问题出在源代码的字符编码上，不知道如何编写，而是复制到记事本中并重新键入“ color：＃445668;”行。 solves the problem. 解决了问题。 Guessing that you are editing linux code on a windows machine or vice versa. 猜测您正在Windows计算机上编辑Linux代码，反之亦然。
