At the root some basic styling variables are defined that can be overwritten by your theme. Some of these can be changed ad hoc by the user in de block-editor. These are:

    --wp--custom--accordion--transition-time: 0.1s;
    --wp--custom--accordion--margin-top: 0px;
    --wp--custom--accordion--margin-right: 0px;
    --wp--custom--accordion--margin-bottom: 0.1em;
    --wp--custom--accordion--margin-left: 0px;
    --wp--custom--accordion--header-padding-top: 0.5em;
    --wp--custom--accordion--header-padding-right: 2em;
    --wp--custom--accordion--header-padding-bottom: 0.5em;
    --wp--custom--accordion--header-padding-left: 2em;
    --wp--custom--accordion--content-padding-top: 0.5em;
    --wp--custom--accordion--content-padding-right: 2em;
    --wp--custom--accordion--content-padding-bottom: 0.5em;
    --wp--custom--accordion--content-padding-left: 2em;
    --wp--custom--accordion--header--text-color: #ffffff;
    --wp--custom--accordion--header--background-color: #666666;
    --wp--custom--accordion--header--active-text-color: #ffffff;
    --wp--custom--accordion--header--active-background-color: #999999;
    --wp--custom--accordion--body--text-color: #ffffff;
    --wp--custom--accordion--body--background-color: #666666;

The default values can also be defined in the theme.json of your (child-) theme:

Add them to the theme.json like so:

{
    "$schema": "https://schemas.wp.org/wp/6.7/theme.json",
    "version": 3,
    "settings": {
        "custom": {
            "accordion": {
                "transitionTime": "0.1s",
                "marginTop": "0px",
                "marginRight": "0px",
                "marginBottom": "0.1em",
                "marginLeft": "0px",
                "headerPaddingTop": "1em",
                "headerPaddingRight": "1em",
                "headerPaddingBottom": "1em",
                "headerPaddingLeft": "1em",
                "contentPaddingTop": "0.5em",
                "contentPaddingRight": "2em",
                "contentPaddingBottom": "0.5em",
                "contentPaddingLeft": "2em",
                "headerTextColor": "#ffffff",
                "headerBackgroundColor" : "#666666",
                "activeHeaderTextColor": "#ffffff"
                "activeHeaderBackgroundColor": "#999999",
                "bodyTextColor": "#000000",
                "bodyBackgroundColor" : "#ffffff",
            }
        }
    }
}<h3>Accessability</h3>The pane-headers have a tab-index. If the Enter-key is pressed while a pane-header has focus, a click-event is triggered on that pane-header thereby activating / opening it.
