Lesson Summary

• Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications.
• Web browsers receive HTML documents from a web server or from local storage and render them into multimedia web pages.
• HTML describes the structure of a web page semantically and originally included cues for the appearance of the document.
• HTML elements are the building blocks of HTML pages.
• With HTML constructs, images and other objects, such as interactive forms, may be embedded into the rendered page.
• HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items.
• HTML elements are delineated by tags, written using angle brackets. Browsers do not display the HTML tags, but use them to interpret the content of the page.
• HTML can embed programs written in a scripting language such as JavaScript which affect the behavior and content of web pages.
• Inclusion of CSS defines the look and layout of content.
• The World Wide Web Consortium (W3C), maintainer of both the HTML and the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.
• The current HTML standard is HTML5, completed and standardized on 28 October 2014.
• HTML markup consists of several key components, including those called tags (and their attributes), character-based data types, character references and entity references.
• HTML tags most commonly come in pairs, although some represent empty elements and so are unpaired. The first tag in such a pair is the start tag, and the second is the end tag. They may also be called opening tags and closing tags.
• The general form of an HTML element is <tag attribute1="value1" attribute2="value2">content</tag>.
• Some HTML elements are defined as empty elements and take the form <tag attribute1="value1" attribute2="value2">.
• If attributes are not mentioned, default values are used in each case.
• A typical HTML document includes:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8">
    <title>Title</title>
  </head>
  <body>
    <p>Hello world!</p>
  </body>
</html>

• The HTML document type declaration, DOCTYPE, triggers standards mode rendering.
• <html> and </html> tags describe the web page.
• <head> and </head> tags describe page metadata.
• meta charset describes page character encoding. The default encoding for HTML5 is UTF-8.
• <title> and </title> tags describe the page title.
• <body> and </body> tags describe the visible page content.
• <p> and </p> tags describe paragraphs.
• <a> and </a> tags describe anchors (hyperlinks).
• <br> tags describe line breaks.
• <h1> and </h1> and similar tags describe content headings.
• <img> tags describe images.
• <!-- and --> enclose comments.
• Special characters may be entered using &code; syntax. Examples include:
  • & - &
  • < - <
  • > - >
• Semantic HTML is a way of writing HTML that emphasizes the meaning of the encoded information over its presentation (look).
• Presentational markup tags are deprecated in current HTML in favor of using CSS to describe content presentation.
