CSS Feedback Examples

Feedback is how an interface says what just happened, or what is happening right now. Spinners, progress bars, toast notifications, alert banners, skeleton placeholders, and confirmation states all belong here, and none of them need JavaScript to move.

Most run on animation rather than stored state: a keyframe starts on load, on hover, or the moment a checkbox flips. The ones that have to be dismissed use :target or a checkbox, so the dismissal sticks. Several of these pages are candid about the limit involved, since a progress bar with no script is choreography rather than measurement. The 13 feedback pages turned up two overflow bugs at 390 pixels wide on October 13, 2026: tooltip directions reached past the screen in every engine, and hover tooltip did the same under WebKit 26.5. Both pages now clip their tooltips.
