Update. Yes, the first clean CSS solution was unsatisfactory. If you dare add some javascript you can do this:
$('.accordion-group').on('show', function() {
$(this).find('.accordion-toggle').removeClass('arrow-down').addClass('arrow-up');
});
$('.accordion-group').on('hide', function() {
$(this).find('.accordion-toggle').removeClass('arrow-up').addClass('arrow-down');
});
It uses bootstrap break events hide
/ show
directly in crash sections. Still without width
/ height
, but otherwise similar to the markup in the OP.
