A better clicking experience?
There is a section in Chapter 4 called ‘A better clicking experience.’ This
section shouldn’t be there. In a previous revision, the button object in the
example was a span element, which meant that the cursor wasn’t a pointer
by default.
Once we changed it to a button element, changing the cursor was no longer
necessary.
In addition, there is no .comment_input element, instead it’s a
.comment-input element (note the dash instead of the underscore).
Thanks to Michael Rasmussen for reporting this!
