 * 1. Grid System 
 * Bootstrap 3 used different breakpoints than Bootstrap 5
 * BS3: xs (<768px), sm (≥768px), md (≥992px), lg (≥1200px)
 * BS5: xs (<576px), sm (≥576px), md (≥768px), lg (≥992px), xl (≥1200px), xxl (≥1400px)

 * This compatibility layer maintains BS3 breakpoints for better compatibility
