Internet
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support email.
World Wide Web
The World Wide Web (abbreviated
as WWW or W3, commonly known as the Web), is
a system of interlinked hypertext documents
accessed via the Internet. With a web browser, one
can view web pages that may contain text, images,
videos, and other multimedia,
and navigate between them via hyperlinks.
Uniform resource locator
A uniform resource locator, abbreviated URL, also
known as web address, is a specific character
string that constitutes a reference to a resource. In
most web browsers, the URL of a web page is
displayed on top inside an address bar. An
example of a typical URL would
be "http://en.example.org/wiki/Main_Page".
HTML Introduction
<!DOCTYPE html> <html> <body> <h1>My First Heading</h1> <p>My first paragraph.</p> </body> </html>
HTML Introduction
Example Explained
The DOCTYPE declaration defines the document type
The text between <html> and </html> describes the web page
The text between <body> and </body> is the visible page content
The text between <h1> and </h1> is displayed as a heading
The text between <p> and </p> is displayed as a paragraph
What is HTML?
HTML is a language for describing web pages.
HTML stands for Hyper Text Markup Language
HTML is a markup language
A markup language is a set of markup tags
The tags describe document content
HTML documents contain HTML tags and plain text
HTML documents are also called web pages
HTML Tags
HTML markup tags are usually called HTML tags
HTML tags are keywords (tag names) surrounded by angle brackets like <html>
HTML tags normally come in pairs like <b> and </b>
The first tag in a pair is the start tag, the second tag is the end tag
The end tag is written like the start tag, with a forward slash before the tag name
Start and end tags are also called opening tags and closing tags
HTML Elements
"HTML tags" and "HTML elements" are often used to
describe the same thing.
But strictly speaking, an HTML element is everything
between the start tag and the end tag, including the
tags:
HTML Element:
<p>This is a paragraph.</p>
Web Browsers
The purpose of a web browser (such as Google
Chrome, Internet Explorer, Firefox, Safari) is to read
HTML documents and display them as web pages.
The browser does not display the HTML tags, but
uses the tags to interpret the content of the page:
The <!DOCTYPE> Declaration
The <!DOCTYPE> declaration helps the browser to
display a web page correctly.
There are many different documents on the web,
and a browser can only display an HTML page
100% correctly if it knows the HTML type and
version used.
Writing HTML Using Notepad or
TextEdit
HTML can be edited by using a professional HTML editor like:
Adobe Dreamweaver
Microsoft Expression Web
CoffeeCup HTML Editor
However, for learning HTML we recommend a text editor like Notepad (PC) or TextEdit (Mac). We believe using a simple text editor is a good way to learn HTML.
Follow the 4 steps below to create your first web page with Notepad.
Step 3: Save Your HTML
Select Save as.. in Notepad's file menu.
When you save an HTML file, you can use either the
.htm or the .html file extension. There is no
difference, it is entirely up to you.
Save the file in a folder that is easy to remember.
Step 4: Run the HTML in Your Browser
Start your web browser and open your html file
from the File, Open menu, or just browse the folder
and double-click your HTML file.
The result should look much like this:
HTML Headings
HTML headings are defined with the <h1> to <h6>
tags.
<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
HTML Paragraphs
HTML paragraphs are defined with the <p> tag.
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
HTML Links
HTML links are defined with the <a> tag.
<a href="http://www.kelsey-
