This step simply selects all the elements with the $(".faq-answer") class and hides them.
Insert the highlighted line 20 in the index.html file in your practice folder, then save.
Line 20 uses the JQuery slideDown method. It is applied to all elements having the faq-answer class. This effectively closes all those elements.
Then on line 21 we use slideUp method to open the element with faq-answer class that is following the code>faq-question class element for the click event on line 13.
Like the slideUp method, the slideDown method arguments are optional and include duration and a callback to an anonymous function when the elements selected are closed.
