Internal CSS is a way of including CSS rules directly within the HTML document using the <style> tag. With internal CSS, you can define styles that apply only to specific elements on a page or to the entire page. Internal CSS is typically used for small websites or pages where you want to keep the CSS code separate from external files.
It refers to CSS styles that are defined within the <head> section of an HTML document, using a <style> element. This allows you to define CSS styles that apply only to the HTML document in which they are defined.
Here is an example of how to use internal CSS:
<!DOCTYPE html>
<html>
<head>
<title>My Webpage</title>
<style>
h1 {
color: blue;
font-size: 24px;
}
p {
color: green;
font-size: 16px;
}
</style>
</head>
<body>
<h1>Welcome to my webpage</h1>
<p>This is some text in a paragraph.</p>
<p>This is another paragraph.</p>
</body>
</html>
In this example, the <style> tag is used to define the styles for the <h1> and <p> elements. The styles are specified using CSS rules, which are enclosed in curly braces. The CSS rules define the color and font size for the <h1> and <p> elements.
Note that the <style> tag must be placed within the <head> section of the HTML document. This ensures that the styles are loaded before the page content, which allows the styles to be applied correctly. Internal CSS can be a useful way to apply simple styles to a webpage without the need for an external stylesheet.
Internal CSS can be useful when you want to apply styles to a single page, but if you want to use the same styles across multiple pages, it's usually better to use an external CSS file. An external CSS file can be linked to multiple HTML documents, allowing you to apply the same styles to all of them.
