This method avoids duplication within a single HTML document. However, it still has its drawbacks: every Web page on your site needs this embedded style sheet inserted; consequently any updates to the style sheet have to be made to every HTML document that has the style sheet embedded in it. We have already used embedded style sheets as they are the simplest to implement, here is another example:

Exercise 3The above code has a deliberate mistake in it. Can you find it? You can find the corrected version at . Notice how rules for the h1, h2, and h3 tags can be simultaneously defined. Embedded style sheets should always be placed within the HEAD — preferably before the TITLE (i.e. not like in the above example). The <style> HTML element contains style information for a document, or part of a document. It contains CSS, which is applied to the contents of the document containing the <style> element. The <style> element must be included inside the <head> of the document. In general, it is better to put your styles in external stylesheets and apply them using <link> elements. If you include multiple <style> and <link> elements in your document, they will be applied to the DOM in the order they are included in the document — make sure you include them in the correct order, to avoid unexpected cascade issues. In the same manner as <link> elements, <style> elements can include <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
2 attributes that contain media queries, allowing you to selectively apply internal stylesheets to your document depending on media features such as viewport width.This element includes the global attributes. This attribute defines which media the style should be applied to. Its value is a media query, which defaults to <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
4 if the attribute is missing.A cryptographic nonce (number used once) used to allow inline styles in a style-src Content-Security-Policy. The server must generate a unique nonce value each time it transmits a policy. It is critical to provide a nonce that cannot be guessed as bypassing a resource's policy is otherwise trivial. This attribute specifies alternative style sheet sets. This attribute explicitly indicates that certain operations should be blocked on the fetching of critical subresources. <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
8-ed stylesheets are generally considered as critical subresources, whereas <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
9 and fonts are not. Deprecated This attribute should not be provided: if it is, the only permitted values are the empty string or a case-insensitive match for <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style media="all and (max-width: 500px)">
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
2.In the following example, we apply a very simple stylesheet to a document: <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: red;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
In this example we've included two <style> elements — notice how the conflicting declarations in the later <style> element override those in the earlier one, if they have equal specificity. <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
In this example we build on the previous one, including a <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style>
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
2 attribute on the second <style> element so it is only applied when the viewport is less than 500px in width.<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style media="all and (max-width: 500px)">
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
Content categories, and if the <!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<title>Test page</title>
<style>
p {
color: white;
background-color: blue;
padding: 5px;
border: 1px solid black;
}
</style>
<style media="all and (max-width: 500px)">
p {
color: blue;
background-color: yellow;
}
</style>
</head>
<body>
<p>This is my paragraph.</p>
</body>
</html>
7 attribute is present: .Permitted contentText content matching the <!DOCTYPE html>
<html lang="en-US">

<style media="all and (max-width: 500px)">

</style>

1 attribute, that is <!DOCTYPE html>
<html lang="en-US">

<style>
p {

background-color: blue;
padding: 5px;

<style media="all and (max-width: 500px)">

background-color: yellow;

</html>
2.Tag omissionNeither tag is omissible.Permitted parentsAny element that accepts .Implicit ARIA rolePermitted ARIA rolesNo <style>0 permittedDOM interface<style>1
The <style> element must be included inside the <head> of the document. In general, it is better to put your styles in external stylesheets and apply them using <link> elements.
The <style> tag takes the 'type' attribute that defines the type of style sheet being used (ie. text/CSS). Example 1: Below is an HTML document with the CSS styling for the entire web page enclosed within the <style></style> tags. These properties would be applied to all corresponding elements in the HTML document.
Which style sheet is known as embedded style sheet?
1) Internal style sheet is also knownas embedded style sheets.
