• Best practices
  • Tailwind v4
  • Custom class name to show the autocompletion (default to className)
  • group-hover with prefix
  • :not in tailwind
  • Color preview doesn’t show in VSCode (preview = a square containing the color before the class)
  • Tailwind’s preflight break existing styles
  • Use both Bootstrap and Tailwind → naming conflicts
  • Problems with Tailwind CSS IntelliSense VSCode extension
  • !important
  • calc
  • @headless-ui's Listbox with createPortal and @floating-ui
