Hi Sherif AMP Development Team, I'm experiencing an issue with CSS implementation in your app. The problem is that your application doesn't support backslash escaping in CSS selectors, which prevents CSS from being recognized properly. Issue: CSS classes like .w-6\/12 and .md\:w-11\/12 are not working because your app doesn't handle the backslash (\) character used for escaping special characters in CSS class names. Impact: Custom CSS with escaped characters fails to load Responsive design implementations are broken Standard CSS frameworks (like Tailwind) that use special characters in class names cannot be used Request: Please update your CSS parser to properly handle backslash escaping so that CSS selectors with escaped forward slashes and colons work correctly. This is a standard CSS feature that should be supported for proper functionality. Thanks for your attention to this matter. Best regards,
