Also,
if (description.style.display == 'block') {
description.style.display = 'none';
return;
firstCell.className = 'start';
secondCell.className = 'end';

}

firstCell and secondCell will never get set in this condition, move return to the end.

if (description.style.display == 'block') {
description.style.display = 'none';
firstCell.className = 'start';
secondCell.className = 'end';
return;
}
