问题
I understand this question has been asked and I'm working with sample code of someone who asked a similar question (Bootstrap accordion, scroll to top of active (open) accordion on click?), but am unable to get it to work in my code.
When a mobile user clicks on a button to view more, the content opens up below the screen. The user would have no idea it's there.
When a user clicks the button to view the content, I would like the content to be scrolled to automatically.
Here is my code: https://jsfiddle.net/bigtime/6yung8vk/2/
JQUERY:
$('.panel-collapse').on('shown.bs.collapse', function(e) {
var $panel = $(this).closest('.panel');
$('html,body').animate({
scrollTop: $panel.offset().top
}, 500);
});

The martial arts were originally aimed towards life preservation and self defense, but today people come to us from all walks of life, each with their own set of reasons for wanting to train at Mousel’s Mixed Martial Arts Academy. Some want to learn self
defense, others want to fight competitively, some seek to become physically fit and others just want to have fun. Whatever the reason you chose, you will find others just like yourself studying at Mousel’s Mixed Martial Arts Academy.
