/resp/ - Responsive Design

when working with [mobile-first] approaches and media queries in css to ensure your site looks great everywhere. a key trick is using a fallback font size of 16px for root element (`html`) declarations, ensuring consistency across devices without needing specific rem values on every tag. for example: [code] * { margin:0; } body{ line-height:2rem; /* simplified instead */ } /* base styles (mobile-first) */ @media(min-width : 768px){ body { font-size:.95em } } in larger screens, you can still control typography using em units while maintaining the base scale set on mobile.
