Note  A comment has the same attributes as the current paragraph style, but is displayed in a different color. Although comments can be viewed while editing a page, they are not visible in the Web browser of a site visitor who has browsed to the page. However, they are visible if the site visitor wants to view the source of your page, so use caution when writing comments.
