List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z ). [1]
some amount of content, including text and other elements; an end tag, in which the element name is prefixed with a slash: </tag>. Raw text elements (also known as text or text-only elements) are constructed with: a start tag (in the form <tag>) marking the beginning of an element, which may incorporate any number of HTML attributes;
The equivalent to an HTML element, a ColdFusion tag begins with the letters "CF" followed by a name that is indicative of what the tag is interpreted to, in HTML. E.g. <cfoutput> to begin the output of variables or other content. In addition to CFScript and plugins (as described), CFStudio provided a design platform with a WYSIWYG display. In ...
HTML documents imply a structure of nested HTML elements. These are indicated in the document by HTML tags, enclosed in angle brackets thus: < p >. [better source needed] In the simple, general case, the extent of an element is indicated by a pair of tags: a "start tag" < p > and "end tag" </ p >. The text content of the element, if any, is ...
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.
As you've already noted, Apple's "k" prefix indicates constants. Typically, the k prefix is followed by type, followed by a more general indication of the item's use. A typical Apple symbol, such ...
The Document Object Model ( DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements ...
