FAQ Accordion Card with CSS and Vanilla Javascript

This challenge was a bit harder for me than the previous one. In particular, the placement of illustration image was hard but at the end I managed to do it nicely. Took some help from @ApplePieGiraffe solution to this challenge like what images should be placed in HTML and hence decided the placement of main desktop and mobile images in the HTML only. Have started to believe that it's a good approach to place the background images or decorative image-based content in CSS instead of HTML. I am glad I have completed another frontend mentor challenge. I will really appreciate any positive feedback on my code.
