Is it possible to format an HTML tooltip?
E.g. I have a DIV with attribute title="foo!". When I have text-size of my browser zoomed in or out in, the text size of the tooltip remains unchanged. Is there a way to make the tooltip font scale with the browser setting?
No. But there are other options out there like Overlib, and jQuery that allow you this freedom.
Personally, I would suggest jQuery as the route to take. It's typically very unobtrusive, and requires no additional setup in the markup of your site (with the exception of adding the jquery script tag in your <head>).
No, it's not possible, browsers have their own ways to implement tooltip. All you can do is to create some div that behaves like an HTML tooltip (mostly it's just 'show on hover') with Javascript, and then style it the way you want.
With this, you wouldn't have to worry about browser's zooming in or out, since the text inside the tooltip div is an actual HTML, it would scale accordingly.
