Go back to Default.aspx and switch to Design View. Beneath the welcome text with the header
and two elements, create a new paragraph (press Enter in Design View) and type some text
(for example, You can log in here). Notice how this new paragraph has a class attribute
called Introduction because VS applies the previous class to new paragraphs automatically.
Remove this class using the Clear Styles option of the Apply Styles window, or manually remove it
from the code in Markup View.
