Introducing CSS—the Language of Web Design

Abstract

Building a website with HTML (Hypertext Markup Language) is only half the story. HTML controls the structure of a web page, using tags such as <p> for paragraphs, <img> for images, and <input> for form elements. This structural role has become even more important with the introduction of semantic elements, such as <article> and <nav>, in HTML5. But HTML says nothing about how the page should look. Th at’s the role of Cascading Style Sheets (CSS). Even default styles are controlled internally by the browser’s own CSS.
