Bubble

A chat message bubble with left and right alignment, semantic color variants, and optional previews for image, audio, file and link attachments. The bubble is only the message surface. Avatars, sender rows and message lists are composed around it with the layout utilities and other components.

Usage

Every part of the bubble is optional. Place any combination of x-h-bubble-header, x-h-bubble-content, x-h-bubble-footer, attachment previews and x-h-bubble-reactions inside an x-h-bubble element. Use data-align="right" for sent messages and the default left alignment for received ones. A <time> element inside the header is automatically de-emphasized.

Accessibility

The bubble itself is a plain container and gets no role. Give the surrounding message list role="log" with aria-live="polite" so new messages are announced, and use <time datetime="..."> for timestamps. The reactions element defaults to role="group" with an accessible name of "Reactions", which you can localize with data-label or override with your own aria-label. Images must carry an alt attribute. Audio attachments render a custom player: the play/pause button and the seek slider (role="slider", operable with the arrow, Home and End keys) get accessible names you can localize with data-play-label, data-pause-label and data-label.

Gallery with more indicator

When a message carries more photos than the four shown, wrap the fourth tile in x-h-bubble-gallery-more and overlay a <button> with a label. The label text is yours to author, so it can be localized (for example +3 or 3 more). Give the button a descriptive aria-label, since the terse label alone does not convey the action.
