DOM Basics

You understand how HTML, CSS, and JavaScript connect to each other to provide fully functional web pages. The structure of the page is built on HTML markup that provides the content.

The typography and visual appearance of the page is made complete by CSS that assigns style to the structure. JavaScript brings interactivity, motion, and dynamism to the page.

We often see HTML markup mixed with styles and scripts, so you probably got used to the phenomenon of these three technologies working together.
