π¨βπΌ Some of our users find the heart icon to be unclear and would like to have a
tooltip that explains what it's for.
π§ββοΈ I've moved things around a little bit to reduce
the amount of code you need to work in. I've also added a simple tooltip
component that's not working quite yet. The positioning is all funny because the
tooltip is being rendered within the context of the card instead of at the root
of the document.
π¨βπΌ Thanks Kellie. Now, let's see if you can make the tooltip component work
properly with a portal.
Note, the change you're making is pretty minimal. You'll also need to change
some of the CSS to make the tooltip look a little better.
Additionally, check the Elements panel in the DevTools to see where the tooltip
is being rendered (next to the button vs
document.body).π¦ Don't forget about the "Files" button in the bottom of this screen. It will
show you which files are changed in this exercise step and allow you to click
to open the relevant files.

Typically you'll want to use a library for tooltips which have been tested for
accessibility best practices. But they're likely using
createPortal under
the hood and you'll very likely find yourself needing to use this API at some
point.
