A website is a sum of many individual parts that make up the anatomy such as the URL, the header, navigation, content, footer etc.
Frequently, we use terms when referring to websites that not everyone knows. Below is the anatomy of a Pratt Engr Template website and the terms used to describe the different regions of a site.
