CSS-in-JS is a styling technique by which JavaScript is used to style components. When this JavaScript is parsed, CSS is generated (usually as a <style> element) and attached into the DOM . It enables the abstraction of CSS to the component level itself, using JavaScript to describe styles in a declarative and maintainable way.
However, a setting only affects other webpages if they use the same CSS selector; e.g. a setting for the selector a.extiw affects fewer pages on the web than one for h2 (but it affects at least all MediaWiki projects, not just one). For lines of CSS which should be different on different MediaWiki projects, e.g. for a different background color ...
In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). [1] [2] A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.
Mapping between HTML5 and JavaScript features and Content Security Policy controls. If the Content-Security-Policy header is present in the server response, a compliant client enforces the declarative allowlist policy.

To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
[6] [3] Sass was designed to both simplify and extend CSS, so things like curly braces were removed from the syntax. Less was designed to be as close to CSS as possible, and as a result existing CSS can be used as valid Less code. [7] The newer versions of Sass also introduced a CSS-like syntax called SCSS (Sassy CSS).
Transitional, in which deprecated elements are allowed; Frameset, in which mostly only frame related elements are allowed. Initially code-named "Cougar", [18] HTML 4.0 adopted many browser-specific element types and attributes, but also sought to phase out Netscape's visual markup features by marking them as deprecated in favor of style sheets ...
Pretty-printing (or prettyprinting) is the application of any of various stylistic formatting conventions to text files, such as source code, markup, and similar kinds of content.
