So the parent node is the newly created div right? So therefore you have to do parent().parent() to remove the entire
newly created section element? I'm asking because otherwise if you create like 10 new pets and remove them, you'll still have extra section elements in the DOM.
Yes that is correct. Doing
$(this).parent().remove(); will remove only the DIV element within the section leaving an empty section behind. Doing
$(this).parent().parent()remove(); will remove the entire section completely.
Alternatively you can also use
$(this).parents('section').remove(); and use a selector as an argument to parents to traverse up the DOM until a match is found so you wont need that extra .parent() method call.
