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 ...
The CSS term font family is matched with the typographical term typeface, which is a grouping of fonts defined by shared design styles. A font is a particular set of glyphs (character shapes), differentiated from other fonts in the same family by additional properties such as stroke weight, slant, relative width, etc.

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 ...
This notably did not include XML's ' (') entity prior to HTML5. For a list of all named HTML character entity references along with the versions in which they were introduced, see List of XML and HTML character entity references. Unnecessary use of HTML character references may significantly reduce HTML readability.
Restrictions may also apply for other reasons. For example, in HTML 4, , which is a reference to a non-printing "form feed" control character, is allowed because a form feed character is allowed. But in XML, the form feed character cannot be used, not even by reference.
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. One example goal of a policy is a stricter execution mode for JavaScript in order to prevent certain cross-site scripting attacks.
