accordion = html.Div(
    dbc.Accordion(
        [
            dbc.AccordionItem(

            ),
        ],
        start_collapsed=True,
    ),
)

Answer 1

To adjust the Item styling, you need to change the styling for .accordion-button<\/code> . To adjust the styling when opening an accordion item, you need to change the styling for .accordion-button:not(.collapsed)<\/code> .

.accordion-button {
    font-size: xx-large;
}

.accordion-button:not(.collapsed) {
    background-color: red;
}
