Q: Does this plugin save any submitted text to my WordPress database?
- A: No. All comparisons are processed on the fly and returned directly to the user’s screen. No data is stored.
Q: Can I change the maximum character limit?
- A: Yes. You can edit the $max = 10000; variable in the PHP code to increase or decrease the allowed limit.
Q:How do I display the Diff Checker on a page?
- A: Simply paste the shortcode [diff_checker] into any WordPress page, post, or widget area.
Q:Why are line breaks crucial for the comparison?
- A: The current comparison algorithm checks differences line by line (split by newlines), making it ideal for code, lists, and structured paragraphs.

Important: Always test new code snippets in a staging environment before pushing them live to production. If you customize the CSS classes (.dc-card, .dc-btn, .added, .removed), ensure your theme stylesheets do not override the default styles.
