overflow-wrap

요약

The overflow-wrap property is used to specify whether or not the browser may break lines within words in order to prevent overflow when an otherwise unbreakable string is too long to fit in its containing box.

Note: Originally a Microsoft (unprefixed) proprietary extension called word-wrap, and implemented by most browsers, it has been renamed to overflow-wrap. The original name word-wrap is now considered an "alternate name" for overflow-wrap.

word-wrap:break-word can be used to work around lack of pre{white-space:pre-wrap} support in IE 5.5-7. See white-space for an example.
IE8 introduced -ms-word-wrap as a synonym for word-wrap. Don't use the -ms- prefix.
