Frequently Asked Questions
Q.How do I use this icon in my React/Next.js project?
You have two choices: install the official package listed under the "REACT IMPORT" tab (e.g. npm install @iconify/react) and import the icon directly, or copy the complete React Component code from the "STANDALONE JSX" tab and paste it directly into a local file (e.g. CriticalDuotoneLineIcon.tsx) to avoid installing any npm packages.
Q.Is this icon free for commercial use?
Yes. This icon is published under the open-source **CC-BY-4.0** license. The license grants full permissions for personal and commercial usage (e.g., in SaaS platforms, client projects, or business landing pages). Attributing the icon creator is generally not required for MIT/ISC licenses, but check details on our dedicated License Guide.
Q.What is the "Download SVG without fill color" toggle?
Many SVGs ship with inline fill="..." attributes. By checking this toggle, we strip these attributes and enforce fill="none", making the SVG fully styleable via CSS classes or Tailwind utility classes like fill-current.
