Examples of css

A style sheet language, or style language, is a computer language that expresses the presentation of structured documents. One attractive feature of structured documents is that the content can be reused in many contexts and presented in various ways. Different style sheets can be attached to the logical structure to produce different presentations.

One modern style sheet language with widespread use is Cascading Style Sheets (CSS), which is used to style documents written in HTML, XHTML and other markup languages.

For content in structured documents to be presented, a set of stylistic rules – describing, for example, colors, fonts and layout – must be applied. A collection of stylistic rules is called a style sheet. Style sheets in the form of written documents have a long history of use by editors and typographers to ensure consistency of presentation, spelling and punctuation. In electronic publishing, style sheet languages are mostly used in the context of visual presentation rather than spelling and punctuation.

Example CSS

To make all paragraphs on a page blue and sized 100% bigger than normal text, we would apply this CSS rule to a page:

 body{
margin:0px;
padding:0px;
 }
 .waper{
height:auto;
width:100%;
overflow:hidden;
 }

.border{
background-color:#FF0;
height:3px;
width:100%;
}
.header{
height:150px;
width:99.3%;
background-color:#000;
border:thick solid #000;
position:relative;
}

Types of css:
There are mainly three types of Css

• Internal css
• External Csee
• inline css
•  

All style sheet languages support some kind of formatting model. Most style sheet languages have a visual formatting model that describes, in some detail, how text and other content is laid out in the final presentation. For example, the CSS formatting model specifies that block-level elements (of which "h1" is an example) extend to fill the width of the parent element. Some style sheet languages also have an aural formatting model.
