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.
Each inner level of the hierarchy is indented by a multiple of this indentation width. White space in code is typically stored as whitespace characters . For a free-form language , indentation is exclusively for the programmer since a code processor (i.e. compiler , interpreter ) ignores whitespace characters.
This is the default style of text alignment on the World Wide Web for left-to-right text. [2] Quotations are often indented. Flush left might also be used in very narrow columns, where full justification would produce too much whitespace between characters or words on some lines.
In these examples the boldface line is the most recently added comment. 1. Your reply to a particular comment should be indented beneath that comment. Indents are achieved by typing one or more leading colon : characters at the very left margin, just before the text you add. In the following example, a single colon was typed just before the "Me ...
A free-format language ignores whitespace characters: spaces, tabs and new lines so the programmer is free to style the code in different ways without affecting the meaning of the code. Generally, the programmer uses style that is considered to enhance readability. The two code snippets below are the same logically, but differ in whitespace.
The template {{}} performs a newline and indents by a specified number of spaces. However, the spaces are not all the same size, but rather a mixture of en-size & em-size spaces that have been tested to work on a wide range of browsers.

Language conventions also affect individual source files. Each compiler (or interpreter) used to process source code is unique. The rules a compiler applies to the source creates implicit standards. For example, Python code is much more consistently indented than, say Perl, because whitespace (indentation) is actually significant to the ...
