 {% capture whats_the_point %}
 
 * Use _element_.remove() to remove an element from the DOM.
 * Remove all children from an element with _element_.children.clear().
 * Function expressions are a convenient way to define single-use functions.
 * => is a shorthand syntax for defining functions that contain just one
 expression.
-* dart:html defines many event-related classes.

 **Try it!**
 Type in the input field and press the return key;
 a new item appears in the list.
 Enter a few more items.
 Point the mouse cursor at one of the items in the list;
 the item turns red and gets slightly larger.
 Click it and it disappears from the list.
 Use the **Delete All** button in the lower right corner of the app
 to remove all of the items in the list at once.

 Specifically, they look at
 the Dart code that removes one or more elements from the DOM
 and the CSS code that makes the text red and larger.
 
 ##Changing the appearance when cursor is over an element {#css-hover}
 
 As you saw, an item in the list turns red and gets bigger
 when the user points at it.
 The mouse cursor also changes shape.
 These visual clues are an important part of the user interface

 We've used this CSS trick
 instead of providing a familiar user interface,
 such as a button with an 'X' on it,
 to keep the code simpler.
 
 ##Removing an element from the DOM tree {#remove-elem}
 
 An element is removed from
 the DOM when it is removed from its parent's list of children.
-The List class provides functions for finding an item in the list
+The
+<a href="https://api.dartlang.org/dart_core/List.html" target="_blank">List</a>
+class provides functions for finding an item in the list
 and removing it.
 But, in this case,
 using the element's remove() function
 is shorter and more concise than
 using functions from the List class.
 
 ![Use element.remove() to remove an element from the DOM](images/remove-element.png)
 
 In the todo_with_delete app,
 the user clicks an item to delete it.
 This is achieved with one line of Dart code.
 When a new to do item is created,
 the code registers a mouse click handler on the new element.

 When the element removes itself from the DOM,
 the browser re-renders the page,
