Study Notes

The World Wide Web (WWW)

The WWW is a method of accessing information on the internet.
Information is contained within web pages and displayed in web browsers.
Web pages are interconnected through hypertext links, allowing users to navigate between them.
The WWW is not synonymous with the internet. The internet is the infrastructure, while the WWW is a service built upon it.

Client-Server Model

This model describes the interaction between networked computers.
Clients request information from servers, which then respond with the requested data.
Any computer can act as a client or server, depending on its primary function.

Hyper Text Markup Language (HTML)

HTML documents are text files with the extension .htm or .html.
They consist of a document type declaration (DTD), tags, character-based content, and entity references.
HTML is case-insensitive, except for the text content.
Spacing is ignored but can enhance readability.
Tags are specific words enclosed in angle brackets and act as containers for content.

Anatomy of an HTML Document

Every HTML page requires a basic template containing elements such as the document type declaration, the root-level html tag, and the head and body sections.

The HTML Template

The first line identifies the document as an HTML document.
The second line marks the beginning and end of the document using the html tag.
The head section provides metadata about the page, including character encoding and the title.
The body section contains the actual content displayed on the webpage.

HTML Tags

Two types of tags exist: enclosing and non-enclosing.
Enclosing tags have both a start and an end tag, while non-enclosing tags have only a start tag.
Tags can be nested, ensuring end tags are placed in reverse order of their start tags.
Ending tags can be closed with /> instead of >, though not mandatory in HTML 5.

Compound Elements

Some tags require other specific tags to function correctly, like the li tag within ol or ul.
These compound elements work together to create structured content.

Attributes

Attributes provide additional information about tags, such as resource locations and display styles.
They follow the syntax attribute-name="attribute-value".
Multiple attributes can be specified for a single tag, separated by spaces.
Quotation marks are recommended, especially for XHTML compatibility.

Frequently Used Tags

Headings are defined using h1 to h6, with h1 being the highest level.
Paragraphs are created using the p tag.
Ordered and unordered lists are created using ol and ul tags, respectively, with li tags for individual list items.
Blockquotes are used for quotations.
The br tag inserts a line break within a paragraph, and the hr tag adds a horizontal rule.

Images

Images are inserted into web pages using the img non-enclosing tag.
The src attribute specifies the image file location.
Allowed locations include URLs, full local paths, and relative paths.
The alt attribute provides alternative text for accessibility purposes, displaying when the image is missing or for voice rendering.
