Today I'm going to talk about a rarely used but extremely useful CSS property, the word-wrap. You can force long (unbroken) text to wrap in a new line by specifying break-word with the word-wrap property. For example, you can use it to prevent text extending out the box and breaking the layout. This commonly happens when you have a long URL in the sidebar or comment list. Word-wrap is supported in IE 5.5+, Firefox 3.5+, and WebKit browsers such as Chrome and Safari.

CSS: Word-Wrap Property (view demo)

You can specify either normal or break-word value with the word-wrap property. Normal means the text will extend the boundaries of the box. Break-word means the text will wrap to next line.

.break-word {
  word-wrap: break-word;

break word
