1.Wht is a CSS File? It
is used for what purpose
CSS stands for "Cascading Style
Sheets", and are used to control and manage font styles, font sizes, and
web site color combinations that are used in a web page. In order to retain
continuity of "look and feel" throughout a website, all pages within
a website will often refer to a single CSS file. The CSS file is typically
contained in a separate file from the website, and the various web pages retrieve
the CSS file each time a web page is displayed. CSS files make global
appearance changes easy -- a single change in a CSS file will mean that any
pages using that CSS file will automatically display the changes
2.How do I make a
picture as a background on my web pages?
Point the body background to the name
of your image you wish to use as the background as shown below. This body line
should be the first line after your < / head> tag.
< body background="picture.gif" >
You can also have the background
image fixed, so it does not move when using the scroll bar in the browser. To
do this add the BGPROPERTIES tag as shown below. < body
background="picture.gif" bgproperties="fixed" >
3.How do I add
scrolling text to my page?
Keep in mind not all browsers support scrolling text. however
to do this add a tag similar to the below example. < marquee >THIS WOULD
SCROLL< /marquee> The above example would create the below scrolling
text. If your browser supports scrolling text the below example should be scrolling.
More examples can be found on our main HTML page that lists most of the HTML
commands.
4.How do I make it so

pictures so that one may be higher or lower than the other?

SRC tag as shown below. < IMG SRC="http://www.computerhope.com/chguy.gif"

6.What is external
Style Sheet? How to link?
External Style Sheet is a
template/document/file containing style information which can be linked with
any number of HTML documents. This is a very convenient way of formatting the
entire site as well as restyling it by editing just one file. The file is
linked with HTML documents via the LINK element inside the HEAD element. Files
containing style information must have extension .css, e.g. style.css. < HEAD > < LINK REL=STYLESHEET
HREF="style.css" TYPE="text/css"> < / HEAD>
7.Is CSS case
sensitive?
Cascading Style Sheets (CSS) is not
case sensitive. However, font families, URLs to images, and other direct
references with the style sheet may be. The trick is that if you write a
document using an XML declaration and an XHTML doctype, then the CSS class
names will be case sensitive for some browsers. It is a good idea to avoid
naming classes where the only difference is the case, for example: div.myclass
{ ...} div.myClass { ... } If the DOCTYPE or XML declaration is ever removed
from your pages, even by mistake, the last instance of the style will be used,
regardless of case.
