The "overflow-wrap" CSS Property


Additional links:

New in CSS3

This property sets whether the browser may break within a word to prevent overflow when an otherwise-unbreakable string is too long to fit within its containing line box.

Values for "overflow-wrap"

CSS 2.1(invalid)

  • This property only has an effect when 'white-space' allows wrapping.
  • This property was originally a Microsoft proprietary property (implemented by most browsers) named "word-wrap", but has been renamed to "overflow-wrap". For maximum compatibility (especially with IE and Edge) use "word-wrap" (which is now considered an alternate name for "overflow-wrap") instead of, or in addition to, "overflow-wrap".
