我有一个情况。我的孩子style.css文件包含以下行：
@import url("../notio-wp/style.css");
Main theme style.css文件包含以下消息：
/*
* PLEASE DO NOT EDIT THIS FILE!
*
* This file is only in your themefolder for WordPress to recognize basic theme data like name and version
* CSS Rules in this file will not be used by the theme.
* Instead use the app.css file that is located in your themes /assets/css/ folder to add your styles.
* If you just want to add small css snippets you might also want to consider to add it to the designated
* CSS option field in your themes backend at: Appearance -> Theme Options
*/
我在custom css主题字段和app.css文件中做了一些修改。
如果我只是将css文件复制到子主题结构中，或仅将app.css修改为app.css，那么将新style.css样式包含在子主题中的最佳方式是什么？在css主要主题字段的custom css行旁边的行select `t1`.`Date` as **`*When*`**,
( select avg(t1.column)
from t1
where `t1.`Date` = `***When***`
) as `Short column name`,
from t1
group by `Date`
order by `Date`
文件中的行？谢谢，
