For this specific case what you can do is to tell browser not to cache your page, by using these meta tags inside <head> tag:
<meta http-equiv='cache-control' content='no-cache'>
<meta http-equiv='expires' content='0'>
<meta http-equiv='pragma' content='no-cache'>
However there are multiple ways to achieve this. You could send the appropriate headers from your back end. Or if you are trying to disable cache temporally you can do it by disabling the browser cache. To do so, Follow below steps.
In your developer tools. Find network tab and disable cache. Like here in the image.
Hope this resolves.

Make a style.css file in your public folder then link this CSS file in your index.html file.
Ex:
<link rel="stylesheet" type="text/css" href="%PUBLIC_URL%/style.css?v=0.0.1" />
Always update the version of this CSS fils before doing build your code.

It's possible, you can simply use jQuery. please take a look at the post How to programmatically empty browser cache?

Even if the below answers didn't work. And you are facing a problem something like your app being cached, making the whole app display an old build then probably you can check this link https://github.com/facebook/create-react-app/issues/1910#issuecomment-355245212. After that do an npm start, it worked for me.

You can use the chrome dev tools. There is an option in the Network Tab to disable the cache.
