Definitions
HTML : HyperText Markup Language – The Language of Web
Pages on the World Wide Web.
HTML is a text formatting language.
URL : Uniform Resource Locator.
Browser :A software program which is used to show webpages.
WWW: A collection of websites or web pages stored in web
servers.Building blocks of webpages connected by hyperlinks and
HTTP
3. 3
“Normal text” surrounded by
bracketed tags that tell browsers
how to display web pages
Pages end with “.htm” or “.html”
Hypertext Markup Language, a
standardized system for tagging
text files to achieve font, colour,
graphic, and hyperlink effects on
World Wide Web pages.
4. 4
Tags
Codes enclosed in brackets
Usually paired
<TITLE>My Web Page</TITLE>
Not case sensitive
<TITLE> = <title> = <TITLE>
But preferably upper case is used

Creating a Basic Starting
Document
<HTML>
<HEAD>
<TITLE>Alva’s Institute of Engineering &Technology</TITLE>
</HEAD>
<BODY>
This is what is displayed on webpage
</BODY>
</HTML>
6. 6
Creating a Basic Starting
Document
The HEAD of your document point to above
window part. The TITLE of your document
appears in the very top line of the user’s
browser.
The text in your TITLE should be as
descriptive as possible because this is what
many search engines, on the internet, use for
indexing your site.
7. 7
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.
<BODY BGCOLOR=“#FFFFFF” text=#000000></BODY>
8. 8
Color Codes
• Colors are set using “RGB” color codes,
which are, represented as hexadecimal
values. Each 2-digit section of the code
represents the amount, in sequence, of
red, green or blue that forms the color. For
example, a RGB value with 00 as the first
two digits has no red in the color.
13. 13
The Body Element
• The BODY element of a web page is an
important element in regards to the page’s
appearance. Here are the attributes of the
BODY tag to control all the levels:
TEXT="#RRGGBB" to change the color of all
the text on the page (full page text color.)
This element contains information about the
page’s background color, the background image,
as well as the text and link colors.
14. 14
Background Color
It is very common to see web pages with
their background color set to white or some
other colors.
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>
15. 15
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>
In this example the document’s page
color is white and the text would be red.
16. 16
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>
17. 17
Headings, <Hx> </Hx>
Inside the BODY element, heading elements
H1 through H6 are generally used for major
divisions of the document. Headings are
permitted to appear in any order, but you will
obtain the best results when your documents
are displayed in a browser if you follow these
guidelines:
1. H1: should be used as the highest level of heading, H2
as the next highest, and so forth.
2. You should not skip heading levels: e.g., an H3 should
not appear after an H1, unless there is an H2 between
them.
19. 19
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.
21. 21
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.
22. 22
Break, <BR>

23. 23
Horizontal Rule, <HR>
The <HR> element causes the
browser to display a horizontal
line (rule) in your document.
<HR> does not use a closing tag,
</HR>.
24. 24
Horizontal Rule, <HR>
Attribute Description Default Value
SIZE Height of the rule in

Some elements have attributes for
alignment (ALIGN) e.g. Headings,
Paragraphs and Horizontal Rules.
The Three alignment values are : LEFT,
RIGHT, CENTER.
<CENTER></CENTER> Will center
elements.
30. 30
Alignment
<DIV ALIGN=“value”></DIV> Represents
a division in the document and can contain
most other element type. The alignment
attribute of the DIV element is well
supported.
<TABLE></TABLE> Inside a TABLE,
alignment can be set for each individual
cell.
31. 31
Special Characters & Symbols
These Characters are recognized in HTML as
they begin with an ampersand and end with with
a semi-colon e.g. &value; The value will either
be an entity name or a standard ASCII character
number. They are called escape sequences.
The next table represents some of the more
commonly used special characters. For a
comprehensive listing, visit the W3C’s section on
special characters at:
http://www.w3.org/MarkUp/HTMLPlus/htmlplus_13.html
33. 33
• Additional escape sequences support accented
characters, such as:
• ö
– a lowercase o with an umlaut: ö
• ñ
– a lowercase n with a tilde: ñ
• È
– an uppercase E with a grave accent: È
NOTE: Unlike the rest of HTML, the escape
sequences are case sensitive. You cannot, for
instance, use < instead of <.

List Elements
HTML supplies several list elements. Most list elements
are composed of one or more <LI> (List Item) elements.
UL : Unordered List. Items in this list start with a list mark
such as a bullet. Browsers will usually change the list
mark in nested lists.
<UL>
<LI> List item …</LI>
<LI> List item …</LI>
</UL>
• List item …
• List item …
37. 37
List Elements
You have the choice of three bullet types: disc(default),
circle, square.
These are controlled in Netscape Navigator by the
“TYPE” attribute for the <UL> element.
<UL TYPE=“square”>
<LI> List item …</LI>
<LI> List item …</LI>
<LI> List item …</LI>
</UL>
List item …

OL: Ordered List. Items in this list are numbered
automatically by the browser.
<OL>
<LI> List item …</LI>
<LI> List item …</LI>
<LI> List item …</LI>
</OL>
1. List item …
2. List item …
3. List item
You have the choice of setting the TYPE Attribute to
one of five numbering styles.

URL (location of the image) E.g.
http://www.domain.com/dir/file.ext or /dir/file.txt.
Alternate Text (ALT): This is a text field that
describes an image or acts as a label. It is
displayed when they position the cursor over a
graphic image.
Alignment (ALIGN): This allows you to align the
image on your page.
49. 49
Images

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.
2) The example below shows how to make the word
Here work as a link to yahoo.
Click <A HREF="http://www.yahoo.com">here</A> to
go to yahoo.
52. 52
LINK, VLINK, and ALINK
These attributes control the colors of the different link
states:
1. LINK – initial appearance – default = Blue.
2. VLINK – visited link – default = Purple.
3. ALINK –active link being clicked–default= Yellow.
The Format for setting these attributes is:
<BODY BGCOLOR=“#FFFFFF” TEXT=“#FF0000”
LINK=“#0000FF”
VLINK=“#FF00FF”
ALINK=“FFFF00”> </BODY>
53. 53
<body LINK="#C0C0C0" VLINK="#808080"
ALINK="#FF0000">
• LINK - standard link - to a page the visitor hasn't
been to yet. (standard color is blue - #0000FF).
VLINK - visited link - to a page the visitor has been to
before. (standard color is purple - #800080).
ALINK - active link - the color of the link when the
mouse is on it. (standard color is red - #FF0000).
If the programmer what to change the color
• Click <a href="http://www.yahoo.com"><font
color="FF00CC">here</font></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
able to get the information quickly. Internal links can help you
meet these goals.
1. Select some text at a place in the document that you would
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>
55. 55
Tables
The <TABLE></TABLE> element has four sub-
elements:
1. Table Row<TR></TR>.
2. Table Header <TH></TH>.
3. Table Data <TD></TD>.
4. Caption <CAPTION></CAPTION>.
The table row elements usually contain table
header elements or table data elements.
58. 58
Tables Attributes
BGColor: Some browsers support background
colors in a table.
Width: you can specify the table width as an
absolute number of pixels or a percentage of the
document width. You can set the width for the
table cells as well.
Border: You can choose a numerical value for
the border width, which specifies the border in
pixels.
CellSpacing: Cell Spacing represents the space
between cells and is specified in pixels.
59. 59
Table Attributes
CellPadding: Cell Padding is the space
between the cell border and the cell
contents and is specified in pixels.
Align: tables can have left, right, or
center alignment.
Background: Background Image, will be
titled in IE3.0 and above.
BorderColor, BorderColorDark.
60. 60
Table Caption
A table caption allows you to specify a line of
text that will appear centered above or bellow
the table.
<TABLE BORDER=1 CELLPADDING=2>
<CAPTION ALIGN=“BOTTOM”> Label For My Table
</CAPTION>
The Caption element has one attribute ALIGN
that can be either TOP (Above the table) or
BOTTOM (below the table).
61. 61
Table Header
Table Data cells are represented by the
TD element. Cells can also be TH (Table
Header) elements which results in the
contents of the table header cells
appearing centered and in bold text.
62. 62
Table Data and Table Header
Attributes
Colspan: Specifies how many cell columns of the table
this cell should span.
Rowspan: Specifies how many cell rows of the table this
cell should span.
Align: cell data can have left, right, or center alignment.
Valign: cell data can have top, middle, or bottom
alignment.
Width: you can specify the width as an absolute number
of pixels or a percentage of the document width.
Height: You can specify the height as an absolute
number of pixels or a percentage of the document height.
65. 65
Table Data and Table Header
Attributes
Column 1 Header Column 2 Header
Row 1 Col 1
Row 2 Col 1 Row 2 Col 2
Row 3 Col 2
66. 66
Special Things to Note
• TH, TD and TR should always have end tags.
Although the end tags are formally optional, many browsers will
mess up the formatting of the table if you omit the end tags. In
particular, you should always use end tags if you have a TABLE
within a TABLE -- in this situation, the table parser gets
hopelessly confused if you don't close your TH, TD and TR
elements.
• A default TABLE has no borders
By default, tables are drawn without border lines. You need the
BORDER attribute to draw the lines.
• By default, a table is flush with the left margin
TABLEs are plopped over on the left margin. If you want
centered tables, You can either: place the table inside a DIV
element with attribute ALIGN="center".
Most current browsers also supports table alignment, using the
ALIGN attribute. Allowed values are "left", "right", or "center", for
example: <TABLE ALIGN="left">. The values "left" and "right"
float the table to the left or right of the page, with text flow
allowed around the table. This is entirely equivalent to IMG
alignment

Frames
Frames are a relatively new addition to the HTML
standard. First introduced in Netscape
Navigator 2.0.
Objectives:
Upon completing this section, you should be able to:
Create a Frame based page.
Work with the Frameset, Frame, and Noframes
elements.
Use the attributes of the Frames elements to
control the display.
Set Targets appropriately.
70. 70
Frames
A framed page is actually made up of multiple
HTML pages. There is one HTML document
that describes how to break up the single
browser window into multiple windowpanes.
Each windowpane is filled with an HTML
document.
For Example to make a framed page with a
windowpane on the left and one on the right
requires three HTML pages. Doc1.html and
Doc2.html are the pages that contain
content. Frames.html is the page that
describes the division of the single browser
window into two windowpanes.
72. 72
Frame Page Architecture
A <FRAMESET> element is placed in the html
document before the <BODY> element. The
<FRAMESET> describes the amount of screen real
estate given to each windowpane by dividing the
screen into ROWS or COLS.
The <FRAMESET> will then contain <FRAME>
elements, one per division of the browser window.
Note: Because there is no BODY container,
FRAMESET pages can't have background images
and background colors associated with them.
74. 74
The Diagram below is a graphical view
of the document described above
FRAMESET COLS=”23%, 77%”
FRAME
NAME=right_pane
SRC= Doc2.html
FRAME
NAME=
left_pane
SRC=Doc1.
html
75. 75
<FRAMESET> Container
<FRAMESET> : The FRAMESET element creates
divisions in the browser window in a single direction.
This allows you to define divisions as either rows or
columns.
ROWS : Determines the size and number of
rectangular rows within a <FRAMESET>. They are set
from top of the display area to the bottom.
Possible values are:
Absolute pixel units, I.e. “360,120”.
A percentage of screen height, e.g. “75%,25%”.
Proportional values using the asterisk (*). This is often
combined with a value in pixels , e.g. “360,*”.
<Frameset cols=“200,20%,*,2*”>
76. 76
Creating a Frames Page
COLS: Determines the size and number of
rectangular columns within a <FRAMESET>.
They are set from left to right of the display
area.
Possible values are:
Absolute pixel units, I.e. “480,160”.
A percentage of screen width, e.g. “75%,25%”.
Proportional values using the asterisk (*). This is
often combined with a value in pixels , e.g.
“480,*”.
77. 77
Creating a Frames Page
FRAMEBORDER : Possible values 0, 1, YES, NO. A
setting of zero will create a borderless frame.
FRAMESPACING: This attribute is specified in
pixels. If you go to borderless frames you will need to
set this value to zero as well, or you will have a gap
between your frames where the border used to be.
BORDER(thickness of the Frame): This attribute
specified in pixels. A setting of zero will create a
borderless frame. Default value is 5.
BORDERCOLOR: This attribute is allows you choose
a color for your border. This attribute is rarely used.
79. 79
<FRAME>
<FRAME>: This element defines a single frame within a
frameset. There will be a FRAME element for each
division created by the FRAMESET element. This tag
has the following attributes:
SRC: Required, as it provides the URL for the page that
will be displayed in the frame.
NAME: Required for frames that will allow targeting by
other HTML documents. Works in conjunction with the
target attribute of the <A>, <AREA>, <BASE>, and
<FORM> tags.
80. 80
Compound FRAMESET Divisions
In this case a second FRAMESET element will
be inserted in the place of the FRAME element
that would describe the second row.
The second FRAMESET element will divide the
remaining screen real estate into 2 columns.
This nested FRAMESET will then be followed by
2 FRAME elements to describe each of the
subsequent frame divisions created.
91. 91
1) <FRAMESET COLS="2*, 3*, 5*">
2) <FRAMESET COLS="150, 20%, *, 3*">
So what are the space-allocation priorities?
Absolute pixel values are always
assigned space first, in order from left to
right. These are followed by percentage
values of the total space. Finally,
proportional values are divided based
upon what space is left.
What do the following mean?
92. 92
• The <FRAME> tag has six associated
attributes: SRC, NAME, MARGINWIDTH,
MARGINHEIGHT, SCROLLING, and
NORESIZE. Here's a complete generic
FRAME:
• <FRAME SRC="url" NAME="window_name"
SCROLLING=YES|NO|AUTO
MARGINWIDTH="value"
MARGINHEIGHT="value"
NORESIZE>
Generic Frame Formula
93. 93
Targets
When you use links for use in a frames environment you
will need to specify an additional attribute called TARGET.
The TARGET attribute uses the NAME attribute of the
FRAME element.
If we were to place a link in doc1.html that linked to
doc3.html and we wanted doc3.html to be displayed in the
right windowpane; the HTML code would appear in
doc1.html as follows:
<A HREF=“doc3.html”
TARGET=“right_pane”>Link to Document 3
</A>
