What is HTML?
3.
4. A small HTML document
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
5. Example Explained
The DOCTYPE declaration defines the document type
to be HTML
The text between <html> and </html> describes an
HTML document
The text between <head> and </head> provides
information about the document
The text between <title> and </title> provides a title
for the document
The text between <body> and </body> describes the
visible page content
The text between <h1> and </h1> describes a heading
The text between <p> and </p> describes a paragraph
6. 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
Tags are not case sensitive
The end tag is written like the start tag, but with
a slash before the tag name
The start tag is often called the opening tag. The end tag is often called
the closing tag.
7. Web Browsers
The purpose of a web browser (Chrome, IE, Firefox,
Safari) is to read HTML documents and display them.
The browser does not display the HTML tags, but uses
them to determine how to display the document:
9. The <!DOCTYPE> Declaration
The <!DOCTYPE> declaration helps the browser to display a
web page correctly.
There are different document types on the web.
To display a document correctly, the browser must know both
type and version.
The doctype declaration is not case sensitive. All cases are
acceptable:
<!DOCTYPE html>
<!DOCTYPE HTML>
<!doctype html>
<!Doctype Html>
11. Open Notepad (PC)
Open Notepad in Windows 8 or later:
Open the Start Screen (the window symbol at the
bottom left on your screen). Type Notepad.
Open Notepad in Windows 7 or earlier:
Click Start (bottom left on your screen). Click All
Programs. Click Accessories. Click Notepad.
12. Write Some HTML
<!DOCTYPE html>
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
13. 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.
UTF-8 is the preferred encoding for HTML files.
ANSI encoding covers US and Western European
characters only.
15. HTML Documents
All HTML documents must start with a type
declaration: <!DOCTYPE html>.
The HTML document itself begins with <html> and
ends with </html>.
The visible part of the HTML document is
between <body> and </body>.
16. 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>
Start tag Element content End tag
<h1> My First Heading </h1>
<p> My first paragraph. </p>
<br>
17. HTML Headings
<h1>This is a Heading 1</h1>
<h2>This is a Heading 2</h2>
<h3>This is a Heading 3</h3>
<h4>This is a Heading 4</h4>
<h5>This is a Heading 5</h5>
<h6>This is a Heading 6</h6>
18. HTML Rules (Lines) <hr/>
<html>
<body>
<p>The hr tag defines a horizontal rule:</p>
<hr />
<p>This is a paragraph</p>
<hr />
<p>This is a paragraph</p>
<hr />
<p>This is a paragraph</p>
</body>
</html>
19.
20. 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"
21. The href Attribute
HTML links are defined with the <a> tag. The link address is
specified in the href attribute:
<a href="http://CTC.com">This is a link</a>
Size Attributes
<img src="w3schools.jpg" width="104" height="142">
The alt Attribute
<img src="w3schools.jpg" alt="W3Schools.com" wid
th="104" height="142">

Setting Document Properties
Document properties are controlled
by attributes of the BODY element.
For example, there are color settings
for the background color of the page,
the document’s text and different
states of links.
30. 33
Background Color
To set your document’s background color,
you need to edit the <BODY> element by
adding the BGCOLOR attribute. The
following example will display a document
with a white background color:
<BODY BGCOLOR=“#FFFFFF”></BODY>
31. 34
TEXT Color
The TEXT attribute is used to control the color
of all the normal text in the document. The
default color for text is black. The TEXT
attribute would be added as follows:
<BODY BGCOLOR=“#FFFFFF”
TEXT=“#FF0000”></BODY>
32. 35
Using Image Background
The BODY element also gives you ability
of setting an image as the document’s
background.
An example of a background image’s
HTML code is as follows:
<BODY BACKGROUND=“hi.gif”
BGCOLOR=“#FFFFFF”></BODY>
33. 36
Previewing Your Work
Once you have created your basic starting
document and set your document properties it
is a good idea to save your file.
To save a file, in NotePad, follow these steps:
1. Locate and click on the menu called “File”.
2. Select the option under File Menu labeled
“Save As”.
3. In the “File Name” text box, type in the entire
name of your file (including the extension
name .html).
34. 37
Headings, <Hx> </Hx>
1. H1: should be used as the highest level of heading, H2
as the next highest, and so forth.
2. Examples <H1>He is a web designer</H1>
1. <H2>He is a web designer</H2>
2. <H3>He is a web designer</H3>
3. <H4>He is a web designer</H4>
4. <H5>He is a web designer</H5>
5. <H6>He is a web designer</H6>
36. 39
Paragraphs, <P> </P>
Paragraphs allow you to add text to a
document in such a way that it will
automatically adjust the end of line to suite
the window size of the browser in which it
is being displayed. Each line of text will
stretch the entire length of the window.
38. 41
Break, <BR>
Line breaks allow you to decide where the text
will break on a line or continue to the end of the
window.
A <BR> is an empty Element, meaning that it
may contain attributes but it does not contain
content.
The <BR> element does not have a closing tag.
39. 42
Break, <BR>

HOW TO MAKE A LINK
1) The tags used to produce links are the <A>
and </A>. The <A> tells where the link should start and
the </A> indicates where the link ends. Everything between
these two will work as a link.

Here work as a link to yahoo.
Click <A HREF="http://www.yahoo.com">yahoo</A> to
go to yahoo.

Internal Links
Internal Links : Links can also be created inside large
documents to simplify navigation. Today’s world wants to be

like to create a link to, then add an anchor to link to like this:
<A NAME=“bookmark_name”></A>
The Name attribute of an anchor element specifies a location
in the document that we link to shortly. All NAME attributes in
a document must be unique.
2. Next select the text that you would like to create as a link to
the location created above.
<A HREF=“#bookmark_name”>Go To Book Mark</A>
