Источник : The Style Information element The 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 element. Try it If you include multiple and 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 elements, 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. 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. 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. @import -ed stylesheets are generally considered as critical subresources, whereas background-image and fonts are not. Deprecated attributes This attribute should not be provided: if it is, the only permitted values are the empty string or a case-insensitive match for text/css . Examples A simple stylesheet 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 pagetitle > style > p color : red; > style > head > body > p > This is my paragraph.p > body > html > Result Multiple style elements In this example we’ve included two elements — notice how the conflicting declarations in the later 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 pagetitle > 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 > Result Including a media query In this example we build on the previous one, including a media attribute on the second 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 pagetitle > 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 > Result Technical summary Content categories Metadata content, and if the scoped attribute is present: flow content.

Three Ways to Insert CSS There are three ways of inserting a style sheet: External CSS With an external style sheet, you can change the look of an entire website by changing just one file! Each HTML page must include a reference to the external style sheet file inside the element, inside the head section. Example External styles are defined within the element, inside the section of an HTML page: This is a heading This is a paragraph. An external style sheet can be written in any text editor, and must be saved with a .css extension. The external .css file should not contain any HTML tags. Here is how the «mystyle.css» file looks: «mystyle.css» body <
    background-color: lightblue; > Note: Do not add a space between the property value (20) and the unit (px): Incorrect (space): margin-left: 20 px; Correct (no space): margin-left: 20px; Internal CSS An internal style sheet may be used if one single HTML page has a unique style. The internal style is defined inside the element, inside the head section. Example Internal styles are defined within the element, inside the section of an HTML page: This is a heading This is a paragraph. Inline CSS An inline style may be used to apply a unique style for a single element. To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property. Example Inline styles are defined within the «style» attribute of the relevant element: This is a heading This is a paragraph. Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly. Multiple Style Sheets If some properties have been defined for the same selector (element) in different style sheets, the value from the last read style sheet will be used. Assume that an external style sheet has the following style for the element: Then, assume that an internal style sheet also has the following style for the element: Example If the internal style is defined after the link to the external style sheet, the elements will be «orange»: Example However, if the internal style is defined before the link to the external style sheet, the elements will be «navy»: Cascading Order What style will be used when there is more than one style specified for an HTML element? All the styles in a page will «cascade» into a new «virtual» style sheet by the following rules, where number one has the highest priority: Inline style (inside an HTML element) External and internal style sheets (in the head section) Browser default So, an inline style has the highest priority, and will override external and internal styles and browser defaults.

: The Style Information element

The 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 element.

Try it

If you include multiple and 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 elements, 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.

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.

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. @import -ed stylesheets are generally considered as critical subresources, whereas background-image and fonts are not.

Deprecated attributes

This attribute should not be provided: if it is, the only permitted values are the empty string or a case-insensitive match for text/css .

Examples

A simple stylesheet

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 pagetitle> style> p  color: red; > style> head> body> p>This is my paragraph.p> body> html> 

Result

Multiple style elements

In this example we’ve included two elements — notice how the conflicting declarations in the later 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 pagetitle> 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> 

Result

Including a media query

In this example we build on the previous one, including a media attribute on the second 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 pagetitle> 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> 

Result

Technical summary

Permitted content Text content matching the type attribute, that is text/css .
Tag omission Neither tag is omissible.
Permitted parents Any element that accepts metadata content.
Implicit ARIA role No corresponding role
Permitted ARIA roles No role permitted

How To Add CSS

When a browser reads a style sheet, it will format the HTML document according to the information in the style sheet.

Three Ways to Insert CSS

There are three ways of inserting a style sheet:

External CSS

With an external style sheet, you can change the look of an entire website by changing just one file!

Each HTML page must include a reference to the external style sheet file inside the element, inside the head section.

Example

External styles are defined within the element, inside the section of an HTML page:

This is a heading

This is a paragraph.

An external style sheet can be written in any text editor, and must be saved with a .css extension.

The external .css file should not contain any HTML tags.

Here is how the «mystyle.css» file looks:

«mystyle.css»

body <
background-color: lightblue;
>

h1 color: navy;
margin-left: 20px;
>

Note: Do not add a space between the property value (20) and the unit (px):
Incorrect (space): margin-left: 20 px;
Correct (no space): margin-left: 20px;

Internal CSS

An internal style sheet may be used if one single HTML page has a unique style.

The internal style is defined inside the element, inside the head section.

Example

Internal styles are defined within the element, inside the section of an HTML page:

This is a heading

This is a paragraph.

Inline CSS

An inline style may be used to apply a unique style for a single element.

To use inline styles, add the style attribute to the relevant element. The style attribute can contain any CSS property.

Example

Inline styles are defined within the «style» attribute of the relevant element:

This is a heading

This is a paragraph.

Tip: An inline style loses many of the advantages of a style sheet (by mixing content with presentation). Use this method sparingly.

Multiple Style Sheets

If some properties have been defined for the same selector (element) in different style sheets, the value from the last read style sheet will be used.

Assume that an external style sheet has the following style for the element:

Then, assume that an internal style sheet also has the following style for the element:

Example

If the internal style is defined after the link to the external style sheet, the elements will be «orange»:

Example

However, if the internal style is defined before the link to the external style sheet, the elements will be «navy»:

Cascading Order

What style will be used when there is more than one style specified for an HTML element?

All the styles in a page will «cascade» into a new «virtual» style sheet by the following rules, where number one has the highest priority:

  1. Inline style (inside an HTML element)
  2. External and internal style sheets (in the head section)
  3. Browser default

So, an inline style has the highest priority, and will override external and internal styles and browser defaults.
