Appearance
Live Stream → Studio → Appearance sets how every stream on the site looks. A preview beside the settings is drawn by the player itself, and changes as you do: switch it between the moments (Before, Live, Ended), between a Viewer's view and the Host's, and between a Wide screen and a Phone. Press Save changes to keep what you set; Reset all to defaults starts over.

Colours and type
| Setting | Choices |
|---|---|
| Theme | Light, Dark, or Automatic: light or dark as each visitor's device is set. Dark paints a card of its own around the player. |
| Accent color | Buttons and highlights. |
| Live badge | The badge's colour on the picture while a stream is live. |
| Corners | How round the player, the chat and the buttons are. |
| Font | The site's, as the theme sets it, or the device's. |
The video itself always sits on black.
Player
| Setting | Choices |
|---|---|
| Shape | Widescreen (16:9), for cameras, screens and OBS; Standard (4:3); or Upright (9:16), for streams from a phone held upright. |
| Title | The stream's title under the player. |
| Time on air | How long the stream has been live, in the player's controls. |
| Names on the video | Who is who, once more than one person is on stage. |
| Viewer count | Shows everyone how many are watching. Hosts always see it. |
| Logo | Your logo over the picture, in a corner, with its width and opacity. A PNG or SVG with a see-through background looks best. |
| Cover | Shown before a stream starts and after it ends. A stream can have its own, in its settings. |
A Stream player block can choose its own shape, time on air and names (Putting a stream on a page).
Chat
| Setting | Choices |
|---|---|
| Position | Beside the stream, as tall as the player and below it on narrow screens, or below the stream. |
| Height | Of the chat below the stream, and on narrow screens. |
| Avatars | Each sender's picture beside their messages. |
| Times | When each message was sent, beside its sender. Otherwise it shows on hover. |
| Emoji picker | The emoji button beside the chat's field. |
| Emoji style | The device's own emoji, or Apple, Google, Twitter or Facebook images, the same on every device. The set's images are downloaded to your site when you save. Better Messages shares this choice. |
Reactions
| Setting | Choices |
|---|---|
| Offered | Which of Heart, Applause, Laughter, Surprise and Fire viewers can send with one tap. None leaves reactions out. |
| Over the picture | Reactions rise over the stream as they come. |
Your own CSS
There is no CSS box of its own: restyle streams with WordPress's Additional CSS (in the Customizer, or in the Site Editor's Styles with a block theme), or in your theme's stylesheet. Every class starts with estream-, and every colour is a CSS custom property starting with --estream-.
