If you're making changes to your CSS file in a Ruby on Rails project and not seeing those changes reflected in the browser, there are a few potential reasons why this might be happening:

1. Asset Pipeline: Ruby on Rails uses the asset pipeline to manage assets like CSS files. When you make changes to your CSS file, you need to ensure that the changes are being picked up by the asset pipeline and compiled properly.

2. Caching: Your browser or the server may be caching the old CSS file, preventing the new changes from being loaded. You've mentioned that you've tried restarting the web server and purging the cache, but sometimes the cache can be stubborn.

3. Precompiled Assets: In production environments, Rails often precompiles assets like CSS files. If you're working in a production environment, you might need to recompile the assets for your changes to take effect.

Here are some steps you can take to troubleshoot the issue:

• Verify File Path: Double-check that you're editing the correct CSS file. In Rails, CSS files are typically located in the app/assets/stylesheets directory.

• Check for Errors: Ensure there are no syntax errors in your CSS file that might be causing it not to load properly.

• Inspect Network Requests: Use your browser's developer tools to inspect the network requests and see if the CSS file is being loaded. If it is, check the response to ensure it's the updated version.

• Disable Caching: Temporarily disable caching in your browser or use "hard refresh" (Ctrl + F5 or Cmd + Shift + R) to force the browser to reload the CSS file.

• Check Environment Settings: If you're working in a production environment, make sure you're recompiling assets after making changes to CSS files. You can do this by running rake assets:precompile or rails assets:precompile depending on your Rails version.

• Clear Browser Cache: Clear your browser cache completely to ensure that it's not holding onto the old CSS file.

• Restart Server: Sometimes, simply restarting your Rails server can resolve caching issues.

• Inspect HTML Markup: Make sure that the CSS file is properly linked in your layout file (application.html.erb or similar) and that there are no typos in the file path.
