CSS

Applying a CSS Theme

You can set a custom theme using the theme property.

Since version 8.0, the bubble always uses the CSS-only mode where the appearance is fully controlled by CSS.

Default CSS Theme

This is the default CSS theme (bubble_default) that is built in. You can use it as a template when creating a custom CSS theme.

.bubble_default_main {
    cursor: default;
    font-family: -apple-system, system-ui, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif;
    font-size: 13px;
}

.bubble_default_main_inner {
    border-radius: 5px;
    padding: 4px;
    color: #666;
    background: #eeeeee;
    background: linear-gradient(to bottom, #ffffff 0%, #eeeeee);
    border: 1px solid #ccc;
    border-radius: 5px;
    box-shadow: 0px 2px 3px rgba(000, 000, 000, 0.3), inset 0px 0px 2px rgba(255, 255, 255, 0.8);
}

.bubble_default_arrow_top {
    fill: #ffffff;
    stroke: #cccccc;
    stroke-width: 1;
}

.bubble_default_arrow_bottom {
    fill: #eeeeee;
    stroke: #cccccc;
    stroke-width: 2;
}

.bubble_default_arrow_left {
    fill: #ffffff;
    stroke: #cccccc;
    stroke-width: 1;
}

.bubble_default_arrow_right {
    fill: #ffffff;
