they seem to act the same, adding elements behind the matched elements. What is different?

The difference is attributes vs. elements.

These do rather different things:

The attr function will get the value of an attribute for an existing element or set one or more attributes on existing elements. The DOM structure remains unchanged.

The append function will add one or more new elements to the DOM structure.

For more details see the jQuery documentation pages for append and attr.

Thank you Steven!
