What is HTML?
HTML is a markup language for describing web documents (web
pages).
• HTML stands for Hyper Text Markup Language
• A markup language is a set of markup tags
• HTML documents are described by HTML tags
• Each HTML tag describes different document content
Ex. -
<html>
<head>
<title>
Page Title
</title>
</head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
HTML Tags
HTML tags are keywords (tag names) surrounded by angle brackets:
<tagname>content</tagname>
• HTML tags normally come in pairs like <p> and </p>
• 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, but with a slash before the tag name
HTML Page Structure
HTML Versions
HTML Editors
HTML can be edited by using professional HTML editors like:
• Microsoft WebMatrix
• Sublime Text
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 1: Open Notepad
• To open Notepad in Windows 7 or earlier:
• Click Start (bottom left on your screen). Click All Programs.
Click Accessories. Click Notepad.
• To open Notepad in Windows 8 or later:
• Open the Start Screen (the window symbol at the bottom left on your
screen). Type Notepad.
Step 2: Write Some HTML
• Write or copy some HTML into Notepad.
<!DOCTYPE html>
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
Step 3: Save the HTML Page
• Save the file on your computer.
• Select File > Save as in the Notepad menu.
• Name the file "index.html" or any other name ending with html or
htm.
View HTML Page in Your Browser
• View HTML Page in Your Browser
HTML Tags
• HTML Headings
HTML headings are defined with the <h1> to <h6> tags.
Example:
<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:
Example:
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
HTML Hyper Links Or Anchor Tag
HTML links are defined with the <a> tag:
Example:
<a href="http://www.skyinfotech.in">Click Here</a>
• The link's destination is specified in the href attribute. That’s why we
called it destination link.
• Attributes are used to provide additional information about HTML
elements.
HTML Images
• HTML images are defined with the <img> tag.
• The source file (src), alternative text (alt), and size (width and height)
are provided as attributes:
Example
<img src=“abc.jpg" alt=“abc.com" width="104" height="142">
HTML Elements
HTML elements are written with a start tag, with an end tag, with
the content in between:
<tagname>content</tagname>
The HTML element is everything from the start tag to the end tag:
<p>My first HTML paragraph.</p>
• HTML tags are not case sensitive: <P> means the
same as <p>.
HTML Attributes
• HTML elements can have attributes
• Attributes provide additional information about an element
• Attributes are always specified in the start tag
• Attributes come in name/value pairs like: name="value"
The lang Attribute:
• The document language can be declared in the <html> tag.
• The language is declared in the lang attribute.
• Declaring a language is important for accessibility
applications (screen readers) and search engines:
The title Attribute
HTML paragraphs are defined with the <p> tag.
In this example, the <p> element has a title attribute.
Example:
<p title=“SEO Class">
SEO Class is a Training program.
It contains all the search engine practices with all on-page SEO and off-
page SEO techniques.
</p>
The href Attribute
HTML links are defined with the <a> tag. The link address is specified in
the href attribute:
Example:
<a href="http://www.skyinfotech.in ">This is a link</a>
Size Attributes
HTML images are defined with the <img> tag.
The filename of the source (src), and the size of the image
(width and height) are all provided as attributes:
Example:
<img src=“abc.jpg" width="104" height="142">
• The image size is specified in pixels: width="104" means 104 screen
pixels wide.
The alt Attribute
• The alt attribute specifies an alternative text to be used, when an
HTML element cannot be displayed.
• The value of the attribute can be read by "screen readers". This way,
someone "listening" to the webpage, i.e. a blind person, can "hear"
the element.
Example:
<img src=“abc.jpg" alt=“abc.com" width="104" height="142">
Chapter Summary
• All HTML elements can have attributes
• The HTML title attribute provides additional "tool-tip" information
• The HTML href attribute provides address information for links
• The HTML width and height attributes provide size information for
images
• The HTML alt attribute provides text for screen readers
HTML Headings
• Headings are defined with the <h1> to <h6> tags.
• <h1> defines the most important heading. <h6> defines the least
important heading.
Example:
<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
Headings Are Important
• Use HTML headings for headings only. Don't use headings to make
text BIG or bold.
• Search engines use your headings to index the structure and content of
your web pages.
• Users skim your pages by its headings. It is important to use headings
to show the document structure.
• h1 headings should be main headings, followed by h2 headings, then
the less important h3, and so on.
HTML Horizontal Rules
• The <hr> tag creates a horizontal line in an HTML page.
• The hr element can be used to separate content:
Example:
<p>This is a paragraph.</p>
<hr>
<p>This is a paragraph.</p>
<hr>
<p>This is a paragraph.</p>
The HTML <head> Element
• The HTML <head> element has nothing to do with HTML headings.
• The HTML <head> element contains meta data. Meta data are not displayed.
• The HTML <head> element is placed between the <html> tag and the <body> tag
Example:
<!DOCTYPE html>
<html>
<head>
<title>My First HTML</title>
<meta charset="UTF-8">
</head>
<body>
Meta Data
• Metadata is "data that provides information about other data". Two
types of metadata exist: structural metadata and
descriptive metadata. Structural metadata is data about the
containers of data. Descriptive metadata uses individual instances of
application data or the data content.
