Merits of Embedded Style Sheets: Multiple tag types can be created in a single document. Styles, in complex situations, can be applied by using Selector and Grouping methods. Extra download is unnecessary. Demerits of Embedded Style Sheets: Multiple documents cannot be controlled.
An embedded style sheet is CSS code included within the HTML document using the tag, affecting only that specific document. A linked style sheet is a separate CSS file linked to the HTML document using the tag, allowing the same stylesheet to be used across multiple HTML documents.
Benefits: One file can be used to control multiple documents having different styles. Multiple HTML elements can have many documents, which can have classes. To group styles in composite situations, methods as selector and grouping are used. Demerits: Extra download is needed to import documents having style information. To render the document, the external style sheet should be loaded. Not practical for small style definitions.
<style type="text/css" media=screen> body{ background-color: gray;} </style>
CSS (Cascading style sheet)
While inline styles in web design uses the same properties that can be found in style sheets, in the way you are meaning style sheets no, inline styles are not style sheets. Inline styles are used when you are needing the use a specific rule once on one page or if you are needing to use a specific rule in place of a rule that would normally get used from an internal or external style sheet. In the cascading priority of things inline styles override internal style sheet rules which override external style sheet rules.
That would refer to the location of the style sheet for your XML document
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.
To edit an already created style sheet and then save it with a new name, first load the style sheet. Then, save the sheet with a new name so that changes will remain separated from the original sheet. Then, make the changes to the sheet using the editing functions.
Cascading Style Sheets (CSS) are used with HTML and XHTML documents as well as dynamic coding languages. CSS is used to control the presentation of these documents predominately in web browsers. By having all the rules that control presentation in one place, you only have to go to one place to make a change and have that change perpetuate across all of the documents that have that style sheet embedded.
An external style sheet.
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");}
To link a style sheet into an HTML document, you will use the <link> tag. This tag links, or embeds, the style sheet into the document. This would look like: <link rel="stylesheet" href="style.css" type="text/css" /> This allows you to use the same style sheet and rules on multiple HTML documents.
