It will be overridden by inline and internal stylesheets. Generally in most circumstances, a well written external one will load faster unless you complicate too much. I usually use two stylesheets on pages; one with the basic declarations and the other with specialized declarations.

When you create an external style sheet for your Web pages, you should name the file following similar naming conventions for your HTML files. When you save it, you use the file extension .css so the browser will recognize that it is a CSS stylesheet.
If you are using an External style sheet, CSS can be changed by embedding CSS code into the HEAD tag after the link to the external CSS file.Embedded CSS must be contained within a STYLE tag.EXAMPLE:
Not sure what is asked, so two answers in one! It can be inline(with the tag,) embedded(in the head) or external(linked in the head.) The other answer deals with external and the declaration of "media" within the link in the Head tag. More than three choices, but relevance and browser support narrow them down since it is up to the browser maker to decide how it is rendered - generally "screen, print and accessiblity(auditory, etc.)

Three Ways to Insert CSSThere are three ways of inserting a style sheet: External style sheetInternal style sheetInline style An external style sheet is ideal when the style is applied to many pages. With an external style sheet, you can change the look of an entire Web site by changing one file. Each page must link to the style sheet using the tag. The tag goes inside the head section: An external style sheet can be written in any text editor. The file should not contain any HTML tags. Your style sheet should be saved with a .css extension. An example of a style sheet file is shown below: hr {color:sienna;}p {margin-left:20px;}body {background-image:URL("images/back40.gif");}
The difference between internal and external style sheets is pretty simple. Both are referenced within the head section of a web page () but external style sheets are much easier to use in the long run, as they allow you to make design changes to an entire site by simply changing one file.In the case of an internal style sheet, styles are referenced within the page itself. For example, your head section may look something like this:When using an external style sheet, the styles are called by using an external page (the file extension is .css) to define the styles for that page. It usually looks much like this:Another great reason to use external style sheets as opposed as internal style sheets is that it keeps your code much shorter in each page, simplifying editing, and since the browser has already loaded the external style sheet once the first page has been loaded, the following pages (if using the same external style sheet) will load faster than if the styles are defined internally.
<link></link>
The advantage of CSS is the ability to style the page dynamically. It has got no such disadvantage to mention.
The conflicting style rules are resolved by introducing internal and external CSS. It defined a common cascading style sheet for all.
The cascading that is referred to in the name cascading style sheets refers to how rules can cascade in how they are implement. CSS rules can be found in three places: an external style sheet, and internal style sheet, or inline. Cascading refers to precedence. A rule located inline, will take precedence over a rule located in an internal style sheet and a rule located in an internal style sheet will take precedence over a rule located in an external style sheet. Within a single style sheet (for example an external style sheet) a rule located at the bottom of the style sheet takes precedence over a rule located at the top of the style sheet. This allows you fine tuned control over your styles and how and when they display and which one will display based upon where in the cascading hierarchy they appear.
