Switching from mobile-first to desktop-first styling can cause layout issues due to the way media queries are structured. Mobile-first design typically uses min-width media queries, while desktop-first uses max-width, which can lead to conflicts if not properly adjusted.

Example Concept: In mobile-first design, styles are applied by default for mobile devices, and media queries using min-width are used to apply styles for larger screens. Conversely, desktop-first design applies styles for larger screens by default, using max-width media queries to adjust for smaller screens. Switching between these approaches requires rethinking the media query logic to ensure styles are applied correctly at each breakpoint.

Additional Comment:

Ensure that your media queries are correctly adjusted from min-width to max-width when switching approaches.
Check for any conflicting styles that may not be overridden correctly due to the change in media query logic.
Review your CSS cascade and specificity to ensure styles are applied as intended.
Test your layout across different devices and screen sizes to identify and fix any issues.
