Expandable box adaptiveApproved

The adaptive version of the expandable box is opened on devices with 768px screen width and higher. On smaller devices it has a clickable arrow to expand the box. Expandable boxes are CSS-only implementations. Thus, you have to follow the markup structure. In other words, it is important to keep the class structure like it is shown in the examples. Note: You can spot H3 and H5 tags being used here. You can use any element according to the requirements as long as you have `.sc-expandable-box__title` class in place.
