Media queries work locally but dont work after deployment to the test environment.

Media queries work in my local but don't work after deployment to the test environment. What could be the reason?   An example:  @media only screen and (max-width : 1300px){  font-size: 12px !important;  }

If your media queries are working locally but not after deployment to the test environment, there are several potential reasons for this issue. Here are some common troubleshooting steps to help you identify and fix the problem:

  1. File Paths:

    • Check if your CSS files and media queries are correctly linked in the HTML file in the deployed environment.
    • Ensure that the paths to your CSS files are correct after deployment. File paths can sometimes be different in local development and test environments.
  2. Caching:

    • Browsers may cache files, and sometimes the cached version might not include the latest changes. Try clearing your browser cache or use "hard reload" (Ctrl + F5 or Shift + Reload) to ensure the latest styles are being applied.
  3. Network Issues:

    • Ensure that there are no network-related issues preventing the proper loading of your CSS files. Check your browser's developer tools for any failed requests or errors.
  4. Server Configuration:

    • Verify that the web server in your test environment is configured to serve CSS files and that there are no restrictions or misconfigurations affecting the delivery of these files.
  5. Specificity Issues:

    • Check if there are other styles in your CSS that might be overriding the styles defined in your media queries. Use browser developer tools to inspect the applied styles and identify any conflicts.
  6. Errors in CSS:

    • Look for syntax errors or typos in your CSS files. A small error can sometimes prevent the entire stylesheet from being applied.
  7. Viewport Meta Tag:

    • Ensure that the viewport meta tag is properly set in the head of your HTML document. This tag is crucial for responsive web design.
  8. Testing in Different Browsers:

    • Test your application in different browsers to see if the issue is specific to one browser. Browser-specific quirks can sometimes affect the rendering of styles.
  9. Server-Side Processing:

    • If there is any server-side processing of the CSS files, make sure it is not altering the content or causing issues with media queries.

By systematically checking these aspects, you should be able to identify and address the issue causing your media queries to not work as expected in the test environment.
