Web Development Layers
Akopọ
Every web page you visit is built from three separate layers that do three different jobs: one holds the content, one decides how it looks, and one makes it react. Pulling these apart is one of the most important ideas in modern web development, because it lets a designer restyle a whole site without touching a word of its text, and lets a writer change the text without breaking the design.
In this lesson you will learn the purpose of each layer: the content layer written in HTML, the presentation layer written in CSS, and the behaviour layer written in a scripting language such as JavaScript. You will see why keeping them in separate files matters and how the three fit together to make a single page. This is the foundation that the rest of website authoring is built on.
