Akkordeon

Erstellen Sie vertikal kollabierende Akkordeons in Kombination mit unserem Collapse-JavaScript-Plugin.

Wie es funktioniert

Das Akkordeon verwendet intern den Zusammenbruch , um es zusammenklappbar zu machen. Um ein erweitertes Akkordeon zu rendern, fügen Sie die .openKlasse in der .accordion.

Der Animationseffekt dieser Komponente ist abhängig von der prefers-reduced-motionMedienanfrage. Weitere Informationen finden Sie im Abschnitt zur reduzierten Bewegung in unserer Dokumentation zur Barrierefreiheit .

Beispiel

Klicken Sie auf die Akkordeons unten, um den Inhalt des Akkordeons zu erweitern/zu reduzieren.

Dies ist der Akkordeonkörper des ersten Elements. Es wird standardmäßig angezeigt, bis das Collapse-Plugin die entsprechenden Klassen hinzufügt, die wir verwenden, um jedes Element zu stylen. Diese Klassen steuern das Gesamterscheinungsbild sowie das Ein- und Ausblenden über CSS-Übergänge. Sie können all dies mit benutzerdefiniertem CSS ändern oder unsere Standardvariablen überschreiben. Es ist auch erwähnenswert, dass fast jeder HTML-Code in die eingefügt werden kann .accordion-body, obwohl der Übergang den Überlauf begrenzt.

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. It's also worth noting that just about any HTML can go within the .accordion-body, though the transition does limit overflow.

Spülen

Hinzufügen .accordion-flush, um die Standardeinstellung background-color, einige Rahmen und einige abgerundete Ecken zu entfernen, um Akkordeons Kante an Kante mit ihrem übergeordneten Container zu rendern.

Variablen

Hinzugefügt in v5.2.0

Als Teil des sich entwickelnden CSS-Variablen-Ansatzes von Bootstrap verwenden Akkordeons jetzt lokale CSS-Variablen .accordionfür eine verbesserte Echtzeit-Anpassung. Die Werte für die CSS-Variablen werden über Sass festgelegt, sodass die Sass-Anpassung auch weiterhin unterstützt wird.
