Acordió

Creeu acordions col·lapsants verticalment en combinació amb el nostre connector de JavaScript de col·lapse.

En aquesta pàgina

Com funciona

L'acordió utilitza el col·lapse internament per fer-lo plegable. Per representar un acordió que s'ha ampliat, afegiu la .openclasse al fitxer .accordion.

L'efecte d'animació d'aquest component depèn de la prefers-reduced-motionconsulta de mitjans. Consulteu la secció de moviment reduït de la nostra documentació d'accessibilitat .

Exemple

Feu clic als acordions següents per ampliar/replegar el contingut de l'acordió.

Aquest és el cos d'acordió del primer element. Es mostra per defecte, fins que el connector de col·lapse afegeix les classes adequades que fem servir per estilitzar cada element. Aquestes classes controlen l'aspecte general, així com la mostra i l'amagat mitjançant transicions CSS. Podeu modificar qualsevol d'això amb CSS personalitzat o anul·lant les nostres variables predeterminades. També val la pena assenyalar que gairebé qualsevol HTML pot anar dins de .accordion-body, encara que la transició limita el desbordament.

This is the second item's accordion body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables. It's also worth noting that just about any HTML can go within the .accordion-body, though the transition does limit overflow.

This is the third item's accordion body. It is hidden by default, until the collapse plugin adds the appropriate classes that we use to style each element. These classes control the overall appearance, as well as the showing and hiding via CSS transitions. You can modify any of this with custom CSS or overriding our default variables.

Les variables

Afegit a la v5.2.0

Com a part de l'evolució de l'enfocament de variables CSS de Bootstrap, els acordions ara utilitzen variables CSS locals activades per .accordiona una personalització millorada en temps real. Els valors de les variables CSS s'estableixen mitjançant Sass, de manera que la personalització de Sass encara és compatible.
