CSS Beautifier
|
||||
---------------
|
||||
|
||||
Written by Harutyun Amirjanyan, (amirjanyan@gmail.com)
|
||||
|
||||
Based on code initially developed by: Einar Lielmanis, <einar@jsbeautifier.org>
|
||||
http://jsbeautifier.org/
|
||||
|
||||
Usage:
|
||||
css_beautify(source_text);
|
||||
css_beautify(source_text, options);
|
||||
|
||||
The options are (default in brackets):
|
||||
indent_size (4) — indentation size,
|
||||
indent_char (space) — character to indent with,
|
||||
preserve_newlines (default false) - whether existing line breaks should be preserved,
|
||||
selector_separator_newline (true) - separate selectors with newline or
|
||||
not (e.g. "a,\nbr" or "a, br")
|
||||
end_with_newline (false) - end with a newline
|
||||
newline_between_rules (true) - add a new line after every css rule
|
||||
space_around_selector_separator (false) - ensure space around selector separators:
|
||||
'>', '+', '~' (e.g. "a>b" -> "a > b")
|
||||
e.g
|
||||
|
||||
css_beautify(css_source_text, {
|
||||
'indent_size': 1,
|
||||
'indent_char': '\t',
|
||||
'selector_separator': ' ',
|
||||
'end_with_newline': false,
|
||||
'newline_between_rules': true,
|
||||
'space_around_selector_separator': true
|
||||
});
