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 ...
The "em" value in CSS refers to the font size of the surrounding text. Common style sheet languages have around ten different units. Value propagation mechanism To avoid having to specify explicitly all values for all properties on all elements, style sheet languages have mechanisms to propagate values automatically.
They are all descendants of Henry IV of France, and ultimately descent from Hugh Capet of the House of Capet. Bruce: David II of Scotland: 1371 The Clan Bruce ruled Scotland from 1306 to 1371. Its last royal member was David II (1324–1371), who died without issue. Upon David's death, the throne passed to his nephew Robert Stewart. The Clan ...
Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms worms or fishes were used within a strict cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically , outside of cladistics, e.g. as a ' grade ', which are fruitless to precisely delineate ...
The law applicable to a British hereditary peerage depends on which Kingdom it belongs to. Peerages of England, Great Britain, and the United Kingdom follow English law; the difference between them is that peerages of England were created before the Act of Union 1707, peerages of Great Britain between 1707 and the Union with Ireland in 1800, and peerages of the United Kingdom since 1800.
CSS does not just apply to visual styling: when spoken out loud by a voice browser, CSS styling can affect speech-rate, stress, richness and even position within a stereophonic image. For these reasons, and in support of a more semantic web, attributes attached to elements within HTML should describe their semantic purpose, rather than merely ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Under conditions of genetic drift alone, every finite set of genes or alleles has a "coalescent point" at which all descendants converge to a single ancestor (i.e. they 'coalesce'). This fact can be used to derive the rate of gene fixation of a neutral allele (that is, one not under any form of selection) for a population of varying size ...
