 ## 3. How JavaScript relates to HTML & CSS
 
 Consider the following analogy. The human body needs 3 essential parts in order to function appropriately: bones, skin and muscles. The bones are necessary to give the body **structure**. The skin (shape of body, hair, clothing, make up) is necessary to give the body a unique **presentation**. and the muscles (for walking, climbing, swimming) are needed to give the body **movement and interactivity**.
 
 This is exactly how HTML, CSS and JavaScript relate to each other:
 
-- HTML is used to put the structure of a website together
-- CSS acts like the skin and makeup for the HTML. CSS improves the colors and layout of a website structure built with HTML
-- JavaScript is a full-on programming language that adds interactivity and functionality to a website

 Each technology has their own file type: `.html`, `.css` and `.js`. The HTML file is always the base, the other files (whether CSS or JavaScript) are then referenced to inside of this HTML file. HTML is the base, because that's the first file a browser will render. That's just how browsers work!
