Cascading Style Sheets
Two types of style sheets: Internal and External
Internal - You insert your style code right into your html code.
These stylesheets should only be used if you are intending to
create a specific page with a specific style. If you want to be
able to make global changes to your website using only one style
sheet, you have to use....
External Stylesheets - Instead of putting all the style code into
your html code, you can create a single document with your css
code and link to it within your webpages code. It would look
something like this
Webpage title< itle> <br><link rel="stylesheet" type="text/css" <br>href="http://www.yourdomain.com/css"> <br></head> <br><br>If you decide to use an internal stylesheet, you have to put your <br>css style wihin the following tags: <br><br><style type="text/css"> <br></style> <br><br>All css or links to the external stylesheets have to go in <br>between the <head> tags <br><br>Now about Css Classes vs. ID's <br><br>The one major difference between a class and an id is that <br>classes can be used multiple times within the same page while an <br>Id can only be used once per page. <br><br>Example: <br><br>ID - The global navigation of your site, or a navigation bar.

google_ad_height = 60;

google_ad_type = "text";
google_ad_channel = "";
google_color_border = "FFFFFF";
google_color_bg = "FFFFFF";

Webpage title< itle>
If you decide to use an internal stylesheet, you have to put your
css style wihin the following tags:
All css or links to the external stylesheets have to go in
between the tags
Now about Css Classes vs. ID's
The one major difference between a class and an id is that
classes can be used multiple times within the same page while an
Id can only be used once per page.
Example:
ID - The global navigation of your site, or a navigation bar. A
footer, header, etc. Only items that appear in only one place
per page.
Class - Anything that you would use multiple times in your page,
such as titles, subtitles, headlines, and the like.
Creating ID 's
To create an Id in your css, you would start with the number sign
(#) and then your label of the id. Here's an example
#navigation {
float:left;
}
To insert the id in your html, you would do something like this
<!-- google_ad_section_end -->
<hr> </div>
<!-- content-wrap ends here --></div>
<!--footer starts here-->
<div id="footer">
