Welcome to the forums @AnnaVarda
The only issue I see with CSS is the 404 on /app.css. This is a hard-coded <link...> in public/index.html however the file app.css does not exist. The App.css in the src directory is imported into App.js
import './App.css';
I suggest you remove the <link href="/app.css" rel="stylesheet" type="text/css" /> from the public/index.html file.
Some of the pages aren’t working properly, for a couple of reasons.
- You need to put a
_redirectsfile inpublicwith the following
/* /index.html 200
This is explained in this section of Netlify’s documentation as well as this forum post. - In the
About.jspage you have<a href=...>links instead of using<Link...>tags fromreact-router-domas done inNavbar.js.
I suggest changing all internal links to<Link...>and leaving<a href=...>for external links only.
