FAQ (Frequently Asked Questions)

• Q: Does this snippet store or send HTML code to my server?
  • A: No. All HTML parsing and formatting happen entirely inside the user’s web browser using JavaScript. No data is stored or transmitted to your server.
• Q: Can I customize the purple color scheme?
  • A: Yes. You can edit the CSS CSS custom variables (--hb-purple and --hb-purple-dark) inside the snippet to match your brand colors.
• Q: Why is my script not executing in the output box?
  • A: That is by design. The tool escapes HTML elements and displays them as formatted plain text to ensure secure rendering.

Disclaimers & Notes

• Always use a child theme or a snippet manager plugin (like Code Snippets) when adding custom PHP code. Direct edits to a parent theme’s functions.php file will be overwritten when the theme updates.
