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.

CSS = Styles and Colors What is CSS? Cascading Style Sheets (CSS) is used to format the layout of a webpage. With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more! Tip: The word cascading means that a style applied to a parent element will also apply to all children elements within the parent. So, if you set the color of the body text to «blue», all headings, paragraphs, and other text elements within the body will also get the same color (unless you specify something else)! Using CSS CSS can be added to HTML documents in 3 ways: Inline — by using the style attribute inside HTML elements Internal — by using a element in the section External — by using a element to link to an external CSS file The most common way to add CSS, is to keep the styles in external CSS files. However, in this tutorial we will use inline and internal styles, because this is easier to demonstrate, and easier for you to try it yourself. Inline CSS An inline CSS is used to apply a unique style to a single HTML element. An inline CSS uses the style attribute of an HTML element. The following example sets the text color of the element to blue, and the text color of the element to red: Example A Blue Heading Internal CSS An internal CSS is used to define a style for a single HTML page. An internal CSS is defined in the section of an HTML page, within a element. The following example sets the text color of ALL the elements (on that page) to blue, and the text color of ALL the elements to red. In addition, the page will be displayed with a «powderblue» background color: Example This is a heading This is a paragraph. External CSS An external style sheet is used to define the style for many HTML pages. To use an external style sheet, add a link to it in the section of each HTML page: Example This is a heading This is a paragraph. The external style sheet can be written in any text editor. The file must not contain any HTML code, and must be saved with a .css extension. Here is what the «styles.css» file looks like: «styles.css»: Tip: With an external style sheet, you can change the look of an entire web site, by changing one file! CSS Colors, Fonts and Sizes Here, we will demonstrate some commonly used CSS properties. You will learn more about them later. The CSS color property defines the text color to be used. The CSS font-family property defines the font to be used. The CSS font-size property defines the text size to be used. Example Use of CSS color, font-family and font-size properties: This is a heading This is a paragraph. CSS Border The CSS border property defines a border around an HTML element. Tip: You can define a border for nearly all HTML elements. Example Use of CSS border property: CSS Padding The CSS padding property defines a padding (space) between the text and the border. Example Use of CSS border and padding properties: CSS Margin The CSS margin property defines a margin (space) outside the border. Example Use of CSS border and margin properties: Link to External CSS External style sheets can be referenced with a full URL or with a path relative to the current web page. Example This example uses a full URL to link to a style sheet: Example This example links to a style sheet located in the html folder on the current web site: Example This example links to a style sheet located in the same folder as the current page: You can read more about file paths in the chapter HTML File Paths. Chapter Summary Use the HTML style attribute for inline styling Use the HTML element to define internal CSS Use the HTML element to refer to an external CSS file Use the HTML element to store and elements Use the CSS color property for text colors Use the CSS font-family property for text fonts Use the CSS font-size property for text sizes Use the CSS border property for borders Use the CSS padding property for space inside the border Use the CSS margin property for space outside the border Tip: You can learn much more about CSS in our CSS Tutorial.

HTML Styles
The HTML style attribute is used to add styles to an element, such as color, font, size, and more.
Example
The HTML Style Attribute
Setting the style of an HTML element, can be done with the style attribute.
The HTML style attribute has the following syntax:
The property is a CSS property. The value is a CSS value.
You will learn more about CSS later in this tutorial.
Background Color
The CSS background-color property defines the background color for an HTML element.
Example
Set the background color for a page to powderblue:
This is a heading
This is a paragraph.
Example
Set background color for two different elements:
This is a heading
This is a paragraph.

: 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>

HTML Styles — CSS
CSS saves a lot of work. It can control the layout of multiple web pages all at once.
CSS = Styles and Colors
What is CSS?
Cascading Style Sheets (CSS) is used to format the layout of a webpage.
With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more!
Tip: The word cascading means that a style applied to a parent element will also apply to all children elements within the parent. So, if you set the color of the body text to «blue», all headings, paragraphs, and other text elements within the body will also get the same color (unless you specify something else)!
Using CSS
CSS can be added to HTML documents in 3 ways:
- Inline — by using the style attribute inside HTML elements
- Internal — by using a element in the section
- External — by using a element to link to an external CSS file
The most common way to add CSS, is to keep the styles in external CSS files. However, in this tutorial we will use inline and internal styles, because this is easier to demonstrate, and easier for you to try it yourself.
Inline CSS
An inline CSS is used to apply a unique style to a single HTML element.
An inline CSS uses the style attribute of an HTML element.
The following example sets the text color of the element to blue, and the text color of the
element to red:
Example
A Blue Heading Internal CSS
An internal CSS is used to define a style for a single HTML page.
An internal CSS is defined in the section of an HTML page, within a element.
The following example sets the text color of ALL the elements (on that page) to blue, and the text color of ALL the
elements to red. In addition, the page will be displayed with a «powderblue» background color:
Example
This is a heading
This is a paragraph.
External CSS
An external style sheet is used to define the style for many HTML pages.
To use an external style sheet, add a link to it in the section of each HTML page:
Example
This is a heading
This is a paragraph.
The external style sheet can be written in any text editor. The file must not contain any HTML code, and must be saved with a .css extension.
Here is what the «styles.css» file looks like:
«styles.css»:
Tip: With an external style sheet, you can change the look of an entire web site, by changing one file!
CSS Colors, Fonts and Sizes
Here, we will demonstrate some commonly used CSS properties. You will learn more about them later.
The CSS color property defines the text color to be used.
The CSS font-family property defines the font to be used.
The CSS font-size property defines the text size to be used.
Example
Use of CSS color, font-family and font-size properties:
This is a heading
This is a paragraph.
CSS Border
The CSS border property defines a border around an HTML element.
Tip: You can define a border for nearly all HTML elements.
Example
Use of CSS border property:
CSS Padding
The CSS padding property defines a padding (space) between the text and the border.
Example
Use of CSS border and padding properties:
CSS Margin
The CSS margin property defines a margin (space) outside the border.
Example
Use of CSS border and margin properties:
Link to External CSS
External style sheets can be referenced with a full URL or with a path relative to the current web page.
Example
This example uses a full URL to link to a style sheet:
Example
This example links to a style sheet located in the html folder on the current web site:
Example
This example links to a style sheet located in the same folder as the current page:
You can read more about file paths in the chapter HTML File Paths.
