Wrap phone numbers in a span with CSS style nowrap to prevent them from breaking across lines

This can be done for any line of text, but I find it most useful for phone number (or other words and numbers containing hyphens).

<span style="white-space:nowrap;">123-456-7890</span>

Here is an example where the phone number wraps to the next line: 123-456-7890

And here is an example where the span keeps the number as a unit: 123-456-7890
