+In this exercise, we want you to build a dynamic shopping list that allows you to add items using a form input and a button. After you type an item in the input field and click the button or press the <kbd>Enter</kbd> key, the following should happen:
 
 - The item should appear in the list.
 - Each item should be given a button that can be pressed to delete that item off the list.
-- The input should be emptied and focused, ready for you to enter another item.
+- Each item should have a button next to it that removes the item from the list when clicked.
+- The input fields should be cleared and focused, ready for the next item entry.
 
 The finished demo will look something like the following — try it out before you build it!
 
 ```html hidden live-sample___dynamic-shopping-list
 <h1>My shopping list</h1>
 
-<div>
+<form>
   <label for="item">Enter a new item:</label>
   <input type="text" name="item" id="item" />
   <button>Add item</button>

 To complete the exercise, follow the steps below, and make sure that the list behaves as described above.
 
-1. To start with, download a copy of our [shopping-list.html](https://github.com/mdn/learning-area/blob/main/javascript/apis/document-manipulation/shopping-list.html) starting file and make a copy of it somewhere. You'll see that it has some minimal CSS, a div with a label, input, and button, and an empty list and {{htmlelement("script")}} element. You'll be making all your additions inside the script.
+1. To begin, download a copy of our [shopping-list.html](https://github.com/mdn/learning-area/blob/main/javascript/apis/document-manipulation/shopping-list.html) starting file and make a copy of it somewhere. You'll see that it has some minimal CSS, a form with a label, input, and button, an empty list, and a {{htmlelement("script")}} element. You'll be making all your additions inside the script.
 2. Create three variables that hold references to the list ({{htmlelement("ul")}}), {{htmlelement("input")}}, and {{htmlelement("button")}} elements.
 3. Create a [function](/en-US/docs/Learn_web_development/Core/Scripting/Functions) that will run in response to the button being clicked.
-4. Inside the function body, start off by storing the current [value](/en-US/docs/Web/API/HTMLInputElement/value) of the input element in a variable.
-5. Next, empty the input element by setting its value to an empty string — `""`.
-6. Create three new elements — a list item ({{htmlelement('li')}}), {{htmlelement('span')}}, and {{htmlelement('button')}}, and store them in variables.
-7. Append the span and the button as children of the list item.
-8. Set the text content of the span to the input element value you saved earlier, and the text content of the button to 'Delete'.
-9. Append the list item as a child of the list.
-10. Attach an event handler to the delete button so that, when clicked, it will delete the entire list item (`<li>...</li>`).
-11. Finally, use the [`focus()`](/en-US/docs/Web/API/HTMLElement/focus) method to focus the input element ready for entering the next shopping list item.
+4. Inside the function body, start by calling [`preventDefault()`](/en-US/docs/Web/API/Event/preventDefault). Since the input is wrapped in a form element, pressing the <kbd>Enter</kbd> key will trigger the form to submit. The call to `preventDefault()` will prevent the form from refreshing the page so a new item can be added to the list instead.
+5. Continue by storing the current [value](/en-US/docs/Web/API/HTMLInputElement/value) of the input in a variable.
+6. Next, clear the input element by setting its value to an empty string (`""`).
+7. Create three new elements — a list item ({{htmlelement('li')}}), a {{htmlelement('span')}}, and a {{htmlelement('button')}} — and store them in variables.
