HTML: HTML, Semantic HTML, CSS, Developer Tools.

  1. HTML (Novice): HTML builds a page from elements, each an opening tag, content and a closing tag, and whether an element is block, inline or inline-block decides how it takes up room on the page.
  2. Semantic HTML (Apprentice): Semantic elements such as strong, nav, main and footer say what their content means, so the HTML describes the content and CSS handles the formatting.
  3. CSS (Novice): A CSS rule finds elements with a selector (by element name, class or id) and formats them with the properties inside its curly braces, such as color, border, width and display.
  4. Developer Tools (Apprentice): Every browser has built-in developer tools that show any element on a page, its HTML and every CSS rule applied to it, so you can find out why a page looks the way it does.
