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.

 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.
