Any external CSS style sheet can be applied to multiple web pages. That is the beauty and the advantage of CSS, one style sheet containing all of your styling rules can control the presentation of hundreds and millions of pages. If you need to change one rule, with CSS you only have to change it in one place and that new rule and style is now used site wide and you only had to make one change.
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");}
CSS (Cascading style sheet)
You should use a style sheet to do this. In between the <head> and </head> tags, place the following: <style type="text/css"> <!-- body {background-color:pink;} //--> </style>
The collection of Graphics that can be applied to web page is Cascading Style Sheet. It can also be abbreviated to CSS.
That would refer to the location of the style sheet for your XML document
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.
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.
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.
In CSS a class is a user-defined selector that can be applied to multiple elements on a single page. In the style sheet when setting the rules for a class you precede your class name with a period. This looks like: .myclassname { font-color: #000000; font-size: 1em; font-weight: normal; } This tells the browser that this is a class and should be applied to any element that has a class="myclassname" as part of the element attributes. For example: <p class="myclassname">This is a paragraph</p> This paragraph would be styled based upon the rules declared above. However the following example would not because it doesn't have a class attribute and it isn't set to myclassname: <p id="myuniqueid">This is a paragraph</p>
