tags
allows you to create distinct divisions on your web page.
They are identified with a unique id. You can then add a
style (css selector) that specifically applies to the div
of that id. Remember to include the DOCTYPE (to render your
page accurately in the browsers) and meta tags (enables
search engines to spider your pages).

wrapper: is the div that wraps around all the other divs
like a container for the page elements.
header: defines the top banner of the page
main: defines the main content of the page
nav: defines the navigation of the page
footer: defines the footer and sub-navigation of the page

2. Create the CSS code - below is the CSS code that styles
the page as a centered 2 column CSS layout with a
navigation bar and a footer. The div#wrapper style creates
the centered box which acts as a container for the rest of
the page content. The width: 80% rule sets the width of the
div. The background-color:#FFFFFF rule creates a white
background for the div. The margin-top: 50px and
margin-bottom: 50px rules create a space of 50 pixels for
the top and bottom margins for the div itself.

The proper way to center a block-level element with CSS is
to set margin-left: auto and margin-right: auto. This
instructs the browser to automatically calculate equal
margins for both sides, thus centering the div. The border:
thin solid #000000 rule adds a border around the outer div.
The rest of the CSS code styles the divs for the header,
footer, nav, and main content.

The div#header and div#footer styles set margins and
padding for those divs. In addition, div#header includes
the text-align: center rule to center the header text, and
div#footer includes the border-top: thin solid #000000 rule
to create a border along the top edge of the div to replace
the horizontal rule above the footer in the table-based
layout.

The div#nav and div#main styles create the two columns in
the middle of the centered box. In the div#nav style, the
float: left rule pushes the div to the left side of its
parent element (the wrapper div), and the width: 25% rule
sets the div's width to 25 percent of the parent element.
With the nav div floated to the left and limited to a set
width, it leaves room for the main div to move up to the
right of the nav div, thus creating the two-column effect.
The div#main style includes the margin-left: 30% rule to
keep the main text aligned in a neat column instead of
spreading out below the nav column. The main div's left
margin is set to a value slightly larger than the width of
the nav div.



3. Create the side navigation menu - to build the left side
navigation I use the normal CSS code for the different
links ie

a:link {

text-decoration: none;

}

a:visited {

text-decoration: none;

}

a:hover {

text-decoration: underline;

color: #FF0000;

}

a:active {

text-decoration: none;

}

If links are placed elsewhere on the page they will inherit
the same properties as above..a blue link that hovers to
red. What if you wish to create another set of links that
are a different color and on passing your mouse over them
they are underlined.

4. Create the bottom navigation - to include this in the
