Comments are made so that you can leave a comment for someone else. It will not display. Notice that the preview pane on the right is blank? This is because all the code is commented out.
Now a comment starts with <!-- and ends with -->. Anything in between them is considered a comment.
If you wanted to uncomment, what would you have to delete?
