We have an FAQ section with one question. Your job is to make it interactive:

In JavaScript:

Add a click event listener to the FAQ question
When clicked, toggle the "show" class on the answer

In CSS:
Add styles so that:

When the FAQ answer has the "show" class, set its opacity to 1 and max-height to 300px
