All the properties and 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 to a single element. It allows you to create and
                 apply a style directly to the element. Syntax to create an inline style is:

                 <element style = “property1:value1; property2:value2; … ….”>

                 Where, element is any valid HTML tag and the style is the global attribute of HTML used by all
                 the tags of HTML. The style attribute contains the CSS properties and their values within double
                 quotes. For example:

                 <body style=”background-color:green; color:white”>

                 Text in white colour
                 </body>

                 Internal Style Sheet

                 CSS design can also be applied to an HTML document by using <STYLE> tag. This tag should be
                 placed inside the <HEAD> and </HEAD> tags. An internal style sheet is commonly used when
                 one web page has a unique style. For example:

                 <head>
                 <style>

                 body{background-color:green; color:white;}
                 </style>

                 </head>
                 <body>

                 Text in white colour

                 </body>
