My locally hosted site has correct CSS and positioning, but once deployed to Heroku, it appears to lose some of its CSS styles. I am using the MERN Stack for this project. I suspect that the issue may be related to my node_modules, even though I have them in my git ignore file and lack expertise in that area. The problem is most evident on my About Us page. This problem seems unusual as most information regarding lost CSS pertains to Rails projects. I have attempted to uninstall/reinstall Bootstrap and added a CDN to the index.js file without success. Any assistance would be greatly appreciated.
Updated Deployed Site Screen Cap
Updated Locally Hosted Screen Cap
UPDATE: I found this CSS library very helpful in resolving my production CSS issues.
