Final Answer:
Internal style sheets are CSS styles embedded within an HTML document, defining the presentation and layout of elements on that specific page. For example, an internal style sheet in HTML can be implemented using the <style> tag within the document's <head> section.
Step-by-step explanation:
Internal style sheets are a method of applying CSS styles directly within an HTML document, encapsulating both content and presentation. To use an internal style sheet, the <style> tag is placed within the <head> section of the HTML document. Within the <style> tag, CSS rules define the styling properties for various HTML elements on that specific page. For instance:
<!DOCTYPE html>
<html>
<head>
<style>
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
}
h1 {
color: #0077cc;
}
</style>
</head>
<body>
<h1>This is a Heading</h1>
<p>This is a paragraph.</p>
</body>
</html>
In this example, the internal style sheet sets the font family, background color, and color of the heading within the HTML document. This approach allows for localized control over the styling of individual pages.
