I'm currently adding verbose tooltips to our site, and I'd like (without having to resort to a whizz-bang jQuery plugin, I know there are many!) to use carriage returns to format the tooltip.
To add the tip I'm using the
<a title='Tool?Tip?On?New?Line'>link with tip</a>
It's so simple you'll kick yourself... just press enter!
<a title='Tool Tip On New Line'>link with tip</a>
Firefox won't display multi-line tooltips at all though - it will replace the newlines with nothing.
