title: removing create react app default styling
body: <p>I use create-react-app and wanted to change the background-color of my body tag, but it seems like there is a default styling overwritten them. Where does those styles come from?
  I didn't see any style being imported nor is it browser default styling.<a href="https://i.stack.imgur.com/lf2fX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/lf2fX.png" alt="enter image description here"></a></p>
