Add another div with a class value of two just below your one element. This will be your second rectangle.
You should not change the existing .one element.
assert(document.querySelectorAll('.one').length === 1);
You should have a second div element in your .canvas element.
assert(document.querySelector('.canvas').children[1].tagName === 'DIV');
Your second div element should have a class value of two.
assert(document.querySelector('.canvas').children[1].className.split(' ').includes('two'));
Your .two element should come after your .one element.
assert(document.querySelector('.two').previousElementSibling.className.split(' ').includes('one'));
