</body>

</html>

Creating Hypertext Links

In creating Hypertext Links, we may include images and other text-level elements.

there is a few things related to link:-

•Link to Absolute URL

–Use a complete URL beginning with http://

•Link to Relative URL

–Use a filename or relative path to filename

•Links to Section

–Use a section name preceded by #

•Link to Section in URL

–Use absolute or relative URL, then #, then section name

•Naming a Section

–Use <A NAME=“….” and do not include the pound sign

for example:-

<html>

<body>

<p>

<a href="#C4">See also Chapter 4.</a>

</p>

<h2>Chapter 1</h2>

<p>This chapter explains .......</p>

<h2>Chapter 2</h2>

<p>This chapter explains ..........</p>

<h2>Chapter 3</h2>

<p>This chapter explains ............</p>

<h2><a name="C4">Chapter 4</a></h2>

<p>This chapter explains ..........</p>

<h2>Chapter 5</h2>

<p>This chapter explains ..................</p>

</body>

</html>

ADDING IMAGES TO DOCUMENT

We can add images to the document that we have made by using IMG-Embedding Images.
This thing has the following attributes:-

–src (required)

–alt (technically required)

–align (see <BR CLEAR=“ALL”>)

–width, height

–hspace, vspace

–border

–usemap, ismap

•Example

<img src=“SomeFile.gif” alt=“My Cat” width=“400” height=“300”>

using this HTML, you can insert images to the document. Lets try it..

<html>

<body>

<p>

An image:

</p>

<p>

A moving image:

</p>

<p>

Note that the syntax of inserting a moving image is no different from a non-moving image.

</p>

</body>

</html>

BUILDING TABLES (TABLE ELEMENTS ATTRIBUTES)

To construct a table, we have to take a few things related to it into account such as:-

•ALIGN

–The ALIGN attribute gives the horizontal alignment of the table as a whole

–Legal values are LEFT, RIGHT and CENTER with LEFT being the default

•BORDER

–This specifies the width in pixels of the border around the table

–This is in addition to the border around each cell (the CELLSPACING)

•CELLSPACING

–This gives the space in pixels between adjacent cells. Drawn as a 3D line if BORDER is nonzero, otherwise empty space in the background color is used

- The default is usually about 3

•CELLPADDING

–CELLPADDING determines the empty space, in pixels, between the cell’s border and the table element

–The default is usually about 1

•WIDTH

–This specifies the width of the table, either in pixels (<TABLE WIDTH=250>) or as a percentage of the current browser window width (<TABLE WIDTH=“75%”>)

•BGCOLOR

–Specify the background color of the TABLE

•BORDERCOLOR, BORDERCOLORDARK, BORDERCOLARLIGHT

–Non standard attributes supported by IE to specify the colors to user for the borders

•BACKGROUND

–This nonstandard attribute supported by IE gives an image file that will be tiled as the background of the table

•RULES

–HTML 4.0 attribute that specifies which inner dividing lines are drawn

–All are drawn if this attribute is omitted

–Legal values are NONE, ROWS, COLS and ALL

•FRAME

–Specifies which outer borders are drawn

–All four are drawn if this attribute is omitted

–Legal values are BORDER or BOX (all), VOID (none), ABOVE (top), BELOW (bottom), HSIDES (top and bottom, despite the somewhat confusing name), VSIDES (left and right), LHS (left), and RHS (right)

Table CAPTION

•Attribute

–ALIGN (Values: TOP, BOTTOM)

•Usage

An enclosing borderless table may give more flexibility than the built-in CAPTION

Heading 1	Heading 2
Row1 Col1 Data	Row1 Col2 Data
Row2 Col1 Data	Row2 Col2 Data
Row3 Col1 Data	Row3 Col2 Data

TR: TABLE Row

TR is used to define each row in the table

Each row will then contain TH and/or TD entries

•ALIGN

–ALIGN (legal values LEFT, RIGHT or CENTER) is used to set the default horizontal alignment for table cells

•VALIGN

–VALIGN (legal values TOP, MIDDLE or BOTTOM) is used to set the default vertical alignment for table cells

•BGCOLOR

–Sets the color for the table row, overriding any values set for the table as a whole via the BGCOLOR attribute of TABLE

•BORDERCOLOR, BORDERCOLORDARK, BORDERCOLARLIGHT

–supported only by IE, these specify the colors to use for the row borders

Table Cells: TH and TD

•COLSPAN

–COLSPAN defines a heading or cell data entry that spans multiple columns

<TR><TH COLSPAN=2>Col 1&2 Heading

<TH>Col13 Heading

<TR><TD>Col1 Data

<TD>Col2 Data

<TD>Col3 Data

</TABLE>

•ROWSPAN

–ROWSPAN defines a heading or cell data entry that spans multiple rows; similar to COLSPAN

•ALIGN

–LEFT, RIGHT, CENTER, JUSTIFY and CHAR

•VALIGN

–TOP, BOTTOM, MIDDLE

•WIDTH, HEIGHT

–Values in pixels only (no percentage officially allowed)

•NOWRAP

–Use with caution

•BGCOLOR, BACKGROUND

–Same as for TABLE and TR

Lets try this as example so that you can have a clear picture about it.

<html>

<body>

<h4>Without cellpadding:</h4>

<tr>

<td>First</td>

</tr>

<tr>

<td>Second</td>

</tr>

</table>

<h4>With cellpadding:</h4>

<table border="1"

cellpadding="10">

<tr>

<td>First</td>

</tr>

<tr>

<td>Second</td>

</tr>

</table>

</body>

</html>
