Normalize.css 没有完全添加reset to react app
Normalize.css does not fully add reset to react app
我正在关注 Reacts 官方网站上的 instructions。我在 src 目录的根目录中有一个 index.css 文件设置，导入如下：
@import-normalize;
然后我在我的 App 组件中导入 index.css 文件：
import '../../index.css';
class App {}
尽管样式表确实存在，但它只是部分 加载重置而不是全部。我在文档中没有看到 add/subtract 您想要的选项。您可以在下面看到添加的内容。现在将其与 full reset.

有两个原因（第二个是主要原因）。
1) 第一个是由于 create react app 中的 browserslist 配置。 Postcss 使用浏览器列表配置来确定哪些样式 keep/remove。最新版本的 CRA 使用此 browserslist 开发配置：
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
如果您将生产配置复制到开发中，您会看到添加了一些样式。例如，overflow: visible; 被添加到 Edge 和 IE 的 hr 元素中。如果你想更清楚地了解项目中将包含的内容和不太远的内容，运行 构建，并查看 static/css/*main.randomletters.chunk 块文件。
2)Postcss-normalize doesn't actually point at the necolas/normalize.css stylesheet you linked. Instead it points at @csstools/normalize.css. Many of the differences you noticed will be there. The author of postcss-normalize (who co-created normalize) says that this version is more actively maintained as the necolas/normalize version includes "non-fixes". I haven't looked into it enough to know whether they're actually non-fixes or not but you can see what he said here: https://github.com/csstools/normalize.css/issues/3。如果您安装了它，请随时 yarn remove normalize.css！
