In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
The purpose of the delimiting tags is to separate PHP code from non-PHP data (mainly HTML). Although rare in practice, PHP will execute code embedded in any file passed to its interpreter, including binary files such as PDF or JPEG files, or in server log files.
To add style to the entire table, add the style element to the § Begin-table delimiter line at the top of the table. Note that in some cases, it may be better to use the style encapsulated in one of the predefined classes; see § Class .
HTML attributes are special words used inside the opening tag to control the element's behaviour. It is a piece of markup language used to adjust the behavior or display of an HTML element.HTML attributes are a modifier of a HTML element type. An attribute either modifies the default functionality of an element type or provides functionality to ...
Any character may be used to separate the values, but the most common delimiters are the comma, tab, and colon. [2]: 113 [5] The vertical bar (also referred to as pipe) and space are also sometimes used. [2]: 113 Column headers are sometimes included as the first line, and each subsequent line is a row of data.
When Whitespace source code is displayed in some browsers, the horizontal spacing produced by a tab character is not fixed, but depends on its location in the text relative to the next horizontal tab stop. Depending on the software, tab characters may also get replaced by the corresponding variable number of space characters.
The table below lists the twenty-five characters defined as whitespace ("WSpace=Y", "WS") characters in the Unicode Character Database. [1] Seventeen use a definition of whitespace consistent with the algorithm for bidirectional writing ("Bidirectional Character Type=WS") and are known as "Bidi-WS" characters.
The MediaWiki Sanitizer.php does some cleanup on attributes. A best practice is to use the proper syntax. Discards attributes not on a whitelist for the given element. Turns broken or invalid entities into plaintext. Double-quotes all attribute values. Attributes without values are given the name as value. Double attributes are discarded.
