Why doesn't break word work on a long string with commas?

Question

I have a long comma delimited string and I\'m trying to use the css style word-wrap:break word but it doesn\'t seem to work on a string without spaces. Is this expected?

Answer 1

word-wrap:break-word; is still experimental, so different browsers might support it or not.

If you have can, insert a zero-width space after the commas. It's U+200B in Unicode, or ​ in HTML. The browser will break the string up at the zero-width space as it needs to. You can probably do that in whatever code is producing the HTML, or write some javascript to automatically insert the character.
