Sample form. The form is enclosed in an HTML table for visual layout. Forms are enclosed in the HTML <form> element. This HTML element specifies the communication endpoint the data entered into the form should be submitted to, and the method of submitting the data, GET or POST.
Where other HTML elements ... for example words ... the use of <legend> elements to identify such divisions and the use of <label> to identify form <input> elements ...
Form, link and image elements could be referenced with a hierarchical name that began with the root document object. A hierarchical name could make use of either the names or the sequential index of the traversed elements. For example, a form input element could be accessed as either document.myForm.myInput or document.forms[0].elements[0].
HTML 4 is an SGML application conforming to ISO 8879 – SGML. [20] April 24, 1998 HTML 4.0 [21] was reissued with minor edits without incrementing the version number. December 24, 1999 HTML 4.01 [22] was published as a W3C Recommendation. It offers the same three variations as HTML 4.0 and its last errata [23] were published on May 12, 2001 ...
In addition to the basics, application-related implementation options and examples, as well as a focus on individual elements of the programming language (so-called "references") are documented. In addition, there is a YouTube channel, which takes up and explains certain topics in web development, and an Internet forum.
Computer language syntax is generally distinguished into three levels: Words – the lexical level, determining how characters form tokens; Phrases – the grammar level, narrowly speaking, determining how tokens form phrases; Context – determining what objects or variables names refer to, if types are valid, etc.
[3] A key characteristic of most markup languages is that they allow intermingling markup with document content such as text and pictures. For example, if a few words in a sentence need to be emphasized, or identified as a proper name, defined term, or another special item, the markup may be inserted between the characters of the sentence.
But if the program is in SSA form, both of these are immediate: y 1 := 1 y 2 := 2 x 1 := y 2. Compiler optimization algorithms that are either enabled or strongly enhanced by the use of SSA include: Constant propagation – conversion of computations from runtime to compile time, e.g. treat the instruction a=3*4+5; as if it were a=17;
