INTRODUCING CSS3
CSS stands for Cascading Style Sheet. It is a design language which enables to simplify the process
of making web pages. It handles and describes how an HTML web page will be presented on a web
browser. It helps to save lot of time as one design layout can be used to make number of web pages.
The latest version of CSS is CSS 3. Earlier, CSS 2 was used.
CSS comprises style rules that are interpreted by the web browser and then applied to the
corresponding elements in HTML web page. Syntax to create a style in CSS is:
selector{property1:value1; property2:value2; … …}
where the selector signifies or points to an HTML tag to which a style will be applied, is a property of
CSS that can be used to create a style and the value1 is the valid value of the property. A semicolon
should be used at the end of the property value if more than one property is used. However, you can
skip the semicolon if only one property is used. All the properties with their values are enclosed within
curly braces. For example, if you want to create a style that fills a background colour in a web page,
then you need to use the background-color property of CSS in the following manner:
body {background-color:green}
In the preceding code, body signifies the <BODY> tag, background-color is the property and green is
the value of property that will change the background colour of the web page as green.
