Byggðu lóðrétt hrynjandi harmonikkur ásamt Collapse JavaScript viðbótinni okkar.

Hvernig það virkar

Harmonikkan notar hrun innvortis til að gera hana fellanlega. Til að gera harmonikku sem er stækkuð skaltu bæta .openbekknum við á .accordion.

Hreyfiáhrif þessa íhluts eru háð prefers-reduced-motionmiðlunarfyrirspurninni. Sjá kaflann um minni hreyfingu í aðgengisskjölunum okkar .

Smelltu á harmonikkurnar hér að neðan til að stækka/minnka innihald harmonikkunnar.

Þetta er harmonikkuhluti fyrsta atriðisins. Það er sjálfgefið sýnt þar til fallviðbótin bætir við viðeigandi flokkum sem við notum til að stíla hvern þátt. Þessir flokkar stjórna heildarútliti, sem og sýningu og felum í gegnum CSS umskipti. Þú getur breytt einhverju af þessu með sérsniðnum CSS eða hnekkt sjálfgefnum breytum okkar. Það er líka athyglisvert að nánast hvaða HTML sem er getur farið innan .accordion-body, þó að umskiptin takmarki flæði.

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.
