We are updating our website
Notice that there are numerous examples of HTML commands prior to the text, but fewer commands within the text itself.
Once in the control panel, you can usually make an FTP account.
You probably ask your neighbors, but you might just fire up your favorite search engine and find one. Or you want a book or clothing item not easily available in stores near you.
Or you can't remember who directed one of your favorite movies. This all means that if you have a business, you need to have an online presence so that new and old customers can find you easily.
So the site editors so not need to know HTML to make changes.
They can update the site from anywhere with an internet connection as long as they have a username and password. So each "page" is a set of information from the database which is displayed within the defined look of the site (known as the template).
