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 ...
They can, therefore, be used by an author to simply insert additional visible space in the resulting output without using spans styled with peculiar values of the CSS "white-space" property. Conversely, indiscriminate use (see the recommended use [citation needed] in style guides), in addition to a normal space, gives extraneous space in the ...
A whitespace character is a character data element that represents white space when text is rendered for display by a computer. For example, a space character (U+0020 SPACE, ASCII 32) represents blank space such as a word divider in a Western script. A printable character results in output when rendered, but a whitespace character does not ...
In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
For example, indenting at the beginning of line means on the left for a left-to-right script and on the right for right-to-left script. Indent is both a noun and a verb. The verb is the act of formatting text to be indented whereas the noun refers to the resulting empty space.
In a typewriter font, <space> will equal  , but will vary according to the font designer's specification in all other fonts, whether proportional or monospace. The HTML standard also specifies display behavior, not just character encoding, so web browsers following the HTML standard will collapse multiple <space>s to a single <space>. Non ...
There will be no text to the right of the table of contents, though an image or a vertical template, such as an infobox, will appear in the space to the right if formatting causes it to require that space. Still, no text will appear in the space in between; it'll be white (as you notice, there is some white space between the TOC box and the ...
Margins on the top or bottom of an element, on the other hand, will not stack or will intermingle. This means that the white space between these elements will be as big as the larger margin between them. The above section refers only to the detailed implementation of CSS rendering and has no relevance to HTML elements themselves.
