## ❓ FAQ & Troubleshooting



### Common Issues



**Q: Animations aren't working on my browser**

A: Animations use CSS transforms and may have limited support on older browsers. Try updating your browser or disabling hardware acceleration if you experience performance issues.



**Q: Eyedropper tool says "not supported"**

A: The EyeDropper API is currently supported in Chrome/Edge 95+. Firefox and Safari support is coming soon. You can still manually enter color values.



**Q: My gradients look different when exported**

A: Some complex gradients with many color stops might render differently across browsers. Test your exported CSS in your target browsers for consistency.



**Q: Local storage data is gone**

A: Favorites and collections are stored in browser local storage. Clear browser data or incognito mode will reset these. Use the export feature to backup your gradients.



**Q: Can I use this for commercial projects?**

A: Yes! This project is MIT licensed, so you can use generated gradients in any project, commercial or personal.



**Q: How do I use the mesh gradient feature?**

A: Enable mesh mode in the Mesh Gradient section, select your grid size, and click on grid points to change colors. You can also randomize for quick variations.



**Q: Can I extract colors from images?**

A: Yes! Use the Color Palette Extraction section to upload images or enter website URLs. The tool will automatically extract the dominant colors.



**Q: How do I test if my gradient is accessible?**

A: Use the Accessibility Checker section to test contrast ratios, simulate color blindness, and get WCAG compliance reports with improvement suggestions.
