Challenge: Create a Form Element

Link to the challenge:

you have to put the <input> element that you already created in the previous challenge inside the <form> element.

As said you have to use the input element that is in the starting code.

<input type="text" placeholder="cat photo URL">

That should be inside the form element and not the empty input element you have now.
