Content Models

The List of Content Models

In HTML, elements typically belonged in either the block level or inline content model. HTML5 introduces seven main content models.

  • - Metadata
  • - Embedded
  • - Interactive
  • - Heading
  • - Phrasing
  • - Flow
  • - Sectioning

Content Models

Metadata: Content that sets up the presentation or behavior of the rest of the content. These elements are found in the head of the document.

  • Elements: <base>, <link>, <meta>, <noscript>, <script>, <style>, <title>

Embedded: Content that imports other resources into the document.

  • Elements: <audio>, <video>, <canvas>, <iframe>, <img>, <math>, <object>, <svg>

Interactive: Content specifically intended for user interaction.

  • Elements: <a>, <audio>, <video>, <button>, <details>, <embed>, <iframe>, <img>, <input>, <label>, <object>, <select>, <textarea>

Heading: Defines a section header.

  • Elements: <h1, <h2, <h3, <h4, <h5, <h6, <hgroup>

Phrasing: This model has a number of inline-level elements in common with HTML4.

  • Elements: <img>, <span, <strong, <label>, br />, <small, <sub, and more.

Flow content: Contains the majority of HTML5 elements that would be included in the normal flow of the document.

Sectioning content: Defines the scope of headings, content, navigation, and footers.

  • Elements: <article>, <aside>, <nav>, <section>

Header, nav & footer

The <header> Element

In HTML4, we would define a header like this:

<div id="header">

In HTML5, a simple <header> tag is used, instead.

The <header> element is appropriate for use inside the body tag.

<!DOCTYPE html>
<html>
   <head></head>
   <body>
      <header>
        <h1> Most important heading </h1>
        <h3> Less important heading </h3>
      </header>
   </body>
</html>
