Check yourself

The layout of the first three products was needed only as a hint. We used it when we put our card together using JavaScript.

Now, when the function for creating a product card is written, it’s time to get rid of the original layout. HTML code must contain empty tag ul.

Feel free to delete all the list elements from the layout, then call the createCard function and add the result of this function to the DOM. That way we will check that the function works correctly.
