How to use Angular component’s styles on WordPress subpage?

I created an application using Angular. It’s really simple, just with four components. After building it with “ng build”, I sent dist file on the server and everything was ok. Problems started when I tried to use my app as a subpage on a website made with WordPress (I have an access to admin panel only). When I insert my index.html code to page’s code editor via admin panel, where I include all script and link tags, my app looks… terrible. It seems, that only main styles.css file works, but all of components’ styles files are ignored. What can I do to fix my problem?
