There is a line of <div style={height: 50px}> where height is 50px i want to make it 0 in code but where it is located?

      It will be replaced with the URL of the `public` folder during the build.

      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`.

  </body>
</html>

There is a white spacing showing and height was the reason so I want to make it 0. I try to find in different files but i don’t know where exactly it is

Any help will be appreciated
Thanks In Advance

I am assuming that you want to find react component responsible for that. You may want to use components tab in developer tools to find out which component is responsible for rendering a particular element. link – https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en With that you can hover on an element and corresponding component gets highlighted.

This looks something like following –
