Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

有一个白色的间距显示，高度是原因，所以我想把它设为0。我试着在不同的文件中查找，但我不知道它的确切位置
如有任何帮助，将不胜感激。

我假设你想要找到对此负责的react组件。您可能希望使用开发人员工具中的components选项卡来找出哪个组件负责呈现特定的元素。link - https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en，您可以将鼠标悬停在元素上，相应的组件将突出显示。
这看起来像下面的内容-
