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 ...
CSS Flexible Box Layout, commonly known as Flexbox, [2] is a CSS web layout model. [4] It is in the W3C 's candidate recommendation (CR) stage. [ 2 ] The flex layout allows responsive elements within a container to be automatically arranged depending on viewport (device screen) size.

Elements of the child navbox can be specified by prepending child n _, subgroup n _, or just n _ to the parameter names (e.g. 1_list1).

Section 4 of the CSS1 specification defines a "formatting model" that gives block-level elements—such as p and blockquote—a width and height, and three levels of boxes surrounding it: padding, borders, and margins.

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 ...
Selectors specify which elements are to be influenced by the style rule. As such, selectors are the glue between the structure of the document and the stylistic rules in the style sheets. In the example above, the "h1" selector selects all h1 elements. More complex selectors can select elements based on, e.g., their context, attributes and content.
Lots of articles exceed the post-expand include size limit due to navboxes taking up a huge amount of bytes. A lot of this is caused by navboxes that include child navboxes, because nesting a navbox template inside another navbox template causes the inner navbox to be counted twice towards the limit (and if you are using the template instead of the module directly, it actually counts 4x).
