The style global attribute contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the element have mainly the purpose of allowing for quick styling, for example for testing purposes.
The style read-only property returns the inline style of an element in the form of a CSSStyleDeclaration object that contains a list of all styles properties for that element with values assigned for the attributes that are defined in the element's inline style attribute.
Note: See the CSS Properties Reference for a list of the CSS properties accessible via style. The style property has the same (and highest) priority in the CSS cascade as an inline style declaration set via the style attribute.
While this property is considered read-only, it is possible to set an inline style by assigning a string directly to the style property. In this case the string is forwarded to CSSStyleDeclaration.cssText. Using style in this manner will completely overwrite all inline styles on the element.
Therefore, to add specific styles to an element without altering other style values, it is generally preferable to set individual properties on the CSSStyleDeclaration object. For example, element.style.backgroundColor = \"red\".
The style property is not useful for completely learning about the styles applied on the element, since it represents only the CSS declarations set in the element's inline style attribute, not those that come from style rules elsewhere, such as style rules in the section, or external style sheets. To get the values of all CSS properties for an element you should use Window.getComputedStyle() instead.
Therefore, to add specific styles to an element without altering other style values, it is generally preferable to set individual properties on the CSSStyleDeclaration object. For example, element.style.backgroundColor = \\\"red\\\".

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.
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 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.
A Mapbox style is a document that defines the visual appearance of a map: what data to draw, the order to draw it in, and how to style the data when drawing it. A style document is a JSON object with specific root level and nested properties. This specification defines and describes these properties.
For platform-appropriate documentation of style-related features, developers using the Mapbox Maps SDK for iOS should consult the iOS SDK API reference, and developers using the Mapbox Maps SDK for macOS should consult the macOS SDK API reference.
A Mapbox style consists of a set of root properties, some of which describe a single global property, and some of which contain nested properties. Some root properties, like version, name, and metadata, don't have any influence over the appearance or behavior of your map, but provide important descriptive information related to your map. Others, like layers and sources, are critical and determine which map features will appear on your map and what they will look like. Some properties, like center, zoom, pitch, and bearing, provide the map renderer with a set of defaults to be used when initially displaying the map.
Note: When a browser reads a style sheet, it will format the HTML document according to the information in the style sheet. 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 (see example below)!
A style guide is a set of standards for the writing, formatting, and design of documents. A book-length style guide is often called a style manual or manual of style (MoS or MOS). (Typical examples include the Chicago Manual of Style and the AMA Manual of Style.) A short style guide, of several pages or several dozen pages, is often called a style sheet, although that term also has multiple other meanings. The standards documented in a style guide can be applied either for general use, or be required usage for an individual publication, a particular organization, or a specific field.
A style guide establishes standard style requirements to improve communication by ensuring consistency both within a document, and across multiple documents. Because practices vary, a style guide may set out standards to be used in areas such as punctuation, capitalization, citing sources, formatting of numbers and dates, table appearance and other areas. The style guide may require certain best practices in writing style, usage, language composition, visual composition, orthography, and typography. For academic and technical documents, a guide may also enforce the best practice in ethics (such as authorship, research ethics, and disclosure) and compliance (technical and regulatory). For translations, a style guide may be used to enforce consistent grammar choices such as tenses, formality levels in tones, and localization decisions such as units of measurements.
Style guides are specialized in a variety of ways, from the general use of a broad public audience, to a wide variety of specialized uses, such as for students and scholars of various academic disciplines, medicine, journalism, the law, government, business in general, and specific industries. The term house style refers to the styling defined by the style guide of a particular publisher or other organization.
Style guides vary widely in scope and size, and writers working in most large industries or professional sectors reference a specific style guide, written for their industry or sector when writing very specialized document types. These guides are useful primarily for only peer-to-peer specialist documentation or to help writers working in specific industries and/or sectors communicate highly technical information in scholarly articles or industry white papers.
Professional reference style guides from different countries give authoritative advice on their language and how to use it, such as the New Oxford Style Manual from Oxford University Press, UK and The Chicago Manual of Style from the University of Chicago Press, US. Australia and Canada both have style guides created by their governments which are available online.
A short style guide is often called a style sheet. A comprehensive guide tends to be long and is often called a style manual or manual of style (MOS or MoS). In many cases, a project such as one book, journal, or monograph series typically has a short style sheet that cascades over the somewhat larger style guide of an organization such as a publishing company, whose content is usually called house style. Most house styles, in turn, cascade over an industry-wide or profession-wide style manual that is even more comprehensive. Some examples of these industry style guides include the following: 1e1e36bf2d
