Q: Does this code permanently alter my theme files?
- A: No. It only minifies the code you manually paste into the input box. It does not touch your theme stylesheets automatically.
Q: Why is there a 200,000 character limit?
- A: The limit ensures your server processes requests smoothly without running out of execution time or memory.
Q: Can I customize the color scheme?
- A: Yes. You can edit the CSS custom properties inside the snippet (--csm-purple, --csm-purple-dark, etc.) to match your brand colors.

Always test minified CSS on a staging environment before pushing changes to a live site.
Keep a backup of your original, unminified CSS files so you can easily edit them in the future.
