Harmonikku
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 .open
bekknum við á .accordion
.
prefers-reduced-motion
miðlunarfyrirspurninni. Sjá
kaflann um minni hreyfingu í aðgengisskjölunum okkar .
