How can I use a carriage return in a HTML tooltip?

I would like to displ开发者_开发知识库ay the "title" attribute tooltip in several lines, so it looks like this:

Line 1
Line 2

I tried to do:

<div title="Line 1\nLine 2">Secret</div>

but it didn't work.

Is that possible?

You can enter 
. In other words:

<div title="Line 1&#10;Line 2">Secret</div>

As stated in How can I use a carriage return in a HTML tooltip? you can just do it like this:

<div title="Line 1  
Line 2">Secret</div>

Though it is said that it doesn't work with Firefox.

Either add new lines within the HTML content itself

<div title="Line 1
Line 2">Secret</div>

Or make your own tooltip using JavaScript and CSS.
