new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

Popover accessibility: no annotations needed

No accessibility annotations are needed for popover component, but keep accessibility considerations in mind if modifying Carbon or creating a custom component.

Popover trigger uses icon button

Popovers use an icon button for the trigger. These buttons are in the tab order and are activated by pressing Enter or Space.

Popover activation toggles open and closed

Pressing Enter or Space on the popover trigger button toggles the popover open and closed, and focus remains on the trigger button.

Popover focus behavior with interactive elements

When the popover contains interactive elements, pressing Tab will move focus to the first component in the popover. When the popover only has non-interactive text, or when the focus is on the last component in the popover, pressing Tab will close the popover and move focus to the next tab stop on the page.

Popover dismissal keyboard shortcuts

The popover can be dismissed by pressing Escape or by pressing Tab when focus is on the last component in the popover.

Popover icon button aria-label

The icon button trigger for a popover has an aria-label attribute that defines or describes what the icon is.

Popover aria-expanded and aria-controls attributes

The popover button uses aria-expanded to set popover visibility and aria-controls to handle navigation to the content.
