Study Notes
HTML Document Structure
- An HTML document contains text and HTML tags.
- Tags define structure and appearance.
- Hyperlinks to other pages or multimedia elements (audio, video, animations) are also included.
- The entire HTML document is confined within and tags.
HTML Tags
- Generally, tags have opening and closing tags.
- Tags are written between
< >brackets. - HTML elements consist of opening and closing tags, content, and attributes.
Basic HTML Structure Example
-
<!DOCTYPE html>: This declaration specifies the version of HTML the document uses. It's typically the first line in an HTML document. -
<html lang="en">: Defines the root element of the HTML document (and sets the language). -
<head>: Contains metadata about the document, such as title, character set. Does not contain visible content. -
<title></title>: Defines the title of the webpage, which displays in the browser tab or window title bar. -
<body>: Contains the visible content of the webpage (text, images, links, other HTML elements, etc).
Table 2-2: Description of the Basic HTML Structure
- No. | HTML element | Description
- 1 |
<!DOCTYPE html>| This declaration specifies the version of HTML (e.g., HTML5) that the document is written in. It's usually the first line of an HTML file.
HTML Hierarchy
- HTML elements are hierarchical (nested).
- This hierarchical structure is called the DOM (Document Object Model)
- The DOM is used by the browser to render the webpage.
Heading Section and Body Section
- Every web document has two primary sections:
- Heading
- Body
- The heading section displays the title. The
headsection starts with<head>tag and ends with</head>tag. The<title>tag is used to specify the title of a webpage. - The body section displays the content of a webpage. The
bodysection starts with<body>tag and ends with</body>tag. Whatever text is specified between thebodytags appears in the browser window.
HTML File
- An HTML file is a text file saved with an .html or .htm extension.
- File extensions help to identify the type of file.
- The most common extension is ".html" although ".htm" used to be common in the past.
- HTML file content includes tags defining web page layout and content (e.g. Text, Tables, Images, Videos, Hyperlinks).
- File extension can be an indication of the file content. This is true for HTML files where the standard text format is often used to store HTML page content. This is true for other file content types as well, for example, image files (.jpg, .png) and sound files (.mp3, .wav)
HTML Metadata
- Metadata is data about data; it describes information about the page content.
- Metadata tags contain information like the page's title, description, keywords, author, and viewport settings that aren't visible to the user.
- Metadata is useful for search engines (SEO) to understand the page content and improve visibility.
Saving and Opening HTML Documents
- To create HTML documents or webpages, two tools are needed - a simple text-editor such as NotePad and a web browser.
