The Code i Copy from link: https://www.tutorialrepublic.com/codelab.php?topic=bootstrap&file=accordion

I just change the button to font

My Problem is:

The code should be toggle but I click 1 more time to close the card body (not working). Only press other collapse then its close.

How to solve this.

Answer 1

The issue you are facing is because <font> have display CSS attribute value inline by default, I would suggest to not using it since its obsolete , to fix the issue I replaced <font> tag with <div>

Note : I also fixed the the collapse attribute for the some of the accordion elements and moved the inline CSS to CSS classes.

 .card-header-title { border-radius:0px; cursor:pointer; }.pe-7s-angle-up-circle { color:#3d68e0; font-size:16px } font { display: block }
