Actual Results

The tooltip content associated with "?" elements are not announced when the triggering elements get activated.

As a result, screen reader users are unable to access the additional information provided by the tooltip.

Expected Results

When the tooltip trigger element receives focus, the associated tooltip content should be announced by screen reader.

Make the tooltip accessible by performing following steps

1. Replace the <span> element with native <button> element in the source code so that it receives keyboard focus.
2. Control the visibility of this <div> element (tooltip content) using CSS depending whether the button is in focused state or not. Ensure that this <div> element does not get dismissed when hovered with mouse. However, the tooltip content can be dismissed on activating “Esc“ key or when it looses focus.
3. specify the ID of the <div> element containing tooltip container to the “aria-describedby“ attribute of the <button> as its value. This will read out the content of tooltip to the screen readers when the button is focused.
4. As well, specify role=”tooltip” attribute to the <div> element containing the tooltip content.

<div role="tooltip" id="tooltip400040" class="..." ...>
Tooltip content goes here ...
</div>
