INTRODUCING CSS3
CSS stands for Cascading Style Sheets. It is used for designing or styling a web page. It handles and
describes how an HTML web page will be presented on a web browser. It helps 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 of the 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, selector signifies or point to an HTML tag to which a style will be applied like <BODY>. The
property1 is a property of CSS that is 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 to green.
Using CSS Style
There are three ways to use the CSS styles in HTML document which are:
Inline style sheet
Internal Style Sheet
External Style Sheet
Inline Style Sheet
An inline style is used to apply a unique style for a single element. It allows you to create and apply a
style on the element. Syntax to create an inline style is:
<element style = "property1:value1; property2:value2; … ….">
