Hi there. Just a few things that would make this a bit easier to use:

1. When the user clicks on the tooltip button, you set the button's aria-describedby as tooltip. Instead of that, let's do the following:

   • On page load, set the aria-live="assertive" to <div id="tootip">.
   • If you do the first step, when the user clicks on a tooltip button, screen readers will announce the tooptip text that appears.
   • Please remove the aria-describedby logic. It shouldn't be there if the tooltip is activated on click (it should remain for the onfocus variation).

2. You have two different types of tooltips -- one on focus and one on click. I would like to keep the onfocus variation, but I'd like to have it in a separate section, with a separate explanation about how it works.

3. Let's change the copy with references of "I" to "We". The "I" implies I wrote it (and I did when I first posted this page, but there are a number of changes you have made that make this better).

4. Put your name on the acknowledgements page. :-)
