Line Break and Empty Paragraph Handling in CKEditor 5
In CKEditor5, the automatic insertion of <br> tags typically occurs due to the editor’s handling of line breaks and empty paragraphs. This behavior is part of the editor’s design to ensure proper formatting and a consistent user experience.
Three Reasons Why CKEditor5 does Automatic <br> Insertions:
Empty Paragraph Handling
CKEditor5 often inserts <br> tags in empty paragraphs to maintain consistency and ensure that empty lines are rendered properly.
Soft Line Breaks
When users press Shift+Enter, CKEditor5 inserts a <br> tag to create a line break within the same paragraph rather than ending the paragraph.
Browser Compatibility
Different browsers handle empty elements and line breaks in varying ways. CKEditor5 uses <br> tags to standardize this behavior across all browsers.
