Web/HTML/Element/style

From Get docs


The HTML <style> 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 media attributes that contain media queries, allowing you to selectively apply internal stylesheets to your document depending on media features such as viewport width.

Attributes

This element includes the global attributes.

type
This attribute defines the styling language as a MIME type (charset should not be specified). This attribute is optional and defaults to text/css if it is not specified; values other than the empty string or text/css are not used. Note: There is very little reason to include this attribute in modern web documents.
media
This attribute defines which media the style should be applied to. Its value is a media query, which defaults to all if the attribute is missing.
nonce
A cryptographic nonce (number used once) used to whitelist 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.
title
This attribute specifies alternative style sheet sets.

Deprecated attributes

scoped ' '

This attribute specifies that the styles only apply to the elements of its parent(s) and children.

This attribute may be re-introduced in the future per https://github.com/w3c/csswg-drafts/issues/3547. If you want to use the attribute now, you can use a polyfill.

Examples

A simple stylesheet

In the following example, we apply a very simple stylesheet to a document:

<!doctype html>
<html>
<head>
  <style>
    p {
      color: red;
    }
  </style> 
</head>
<body>
  <p>This is my paragraph.</p>
</body>
</html>

Multiple style elements

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>
<head>
  <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>

Including a media query

In this example we build on the previous one, including a media attribute on the second <style> element so it is only applied when the viewport is less than 500px in width.

<!doctype html>
<html>
<head>
  <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>
