All challenges may appear broken by default since they contain whitespace sections where you need to input the necessary code. Once you correctly fill in these whitespace sections, the completed code will be displayed on the live page.

Additionally, every challenge features two buttons: Hint and Solution. Clicking on Hint provides small hints for the current challenge, while selecting the Solution button opens a new tab with the completed challenge.
