<!doctype html>
<html>
<body>
<h1 style= "font-family:arial black; color:blue">
Inforica Pvt lmd
</h1>
</body>
</html>
- Internal CSS : When CSS styles are defined within the head section then it is called as Internal CSS. While defining CSS in the head section. CSS style will have three main parts- Selector, Property and Value. Selector is used to specify the HTML element for which you are defining the style. property is used to specify the CSS property you want to set and value is used to specify the value for CSS property. Property and its value must be separated by colon and multiple properties must be separated by semicolon.
Eg: The following example defines styles for the elements h1 and h2 as internal CSS.
<!doctype html>
<html>
<head>
<style type = "text/CSS">
<h1>
{
font-family:arial black; color:blue"
}
<h2>
{
font-family:times new roman; color:red"
}
</style>
</head>
<body>
<h1> Inforica Pvt lmt </h1>
<h2> Inforica Pvt lmt </h2>
<h1> Inforica Pvt lmt </h1>
<h1> Inforica Pvt lmt </h1>
</body>
</html>
