Bootstrap accordion with large arrow icon
This has a beautiful simple accordion example. Unlike other examples where panel-group was used, this uses the card with each card acting as an accordion. This contains the card header and card body. Take a look at the class used for header and body they define the collapsible feature. By default the first card is expanded, where are others are made false. The card-body is just defining the matter which would be displayed in the accordion. The accordion container is used to hold these set of cards, whose titles are visible but only one pane is visible at a time. The CSS styling has added extra look and transitions for this Accordion. This snippet is responsive and changes to the look to fit the screen size. You can easily use this sample to add a stylish look to your page.
