32 | Written by Harutyun Amirjanyan, (amirjanyan@gmail.com) |
||
33 | |||
34 | Based on code initially developed by: Einar Lielmanis, <einar@jsbeautifier.org> |
||
35 | http://jsbeautifier.org/ |
||
36 | |||
37 | Usage: |
||
38 | css_beautify(source_text); |
||
39 | css_beautify(source_text, options); |
||
40 | |||
41 | The options are (default in brackets): |
||
42 | indent_size (4) — indentation size, |
||
43 | indent_char (space) — character to indent with, |
||
44 | preserve_newlines (default false) - whether existing line breaks should be preserved, |
||
45 | selector_separator_newline (true) - separate selectors with newline or |
||
46 | not (e.g. "a,\nbr" or "a, br") |
||
47 | end_with_newline (false) - end with a newline |
||
48 | newline_between_rules (true) - add a new line after every css rule |
||
49 | space_around_selector_separator (false) - ensure space around selector separators: |
||
50 | '>', '+', '~' (e.g. "a>b" -> "a > b") |
||
51 | e.g |
||
52 | |||
53 | css_beautify(css_source_text, { |
||
54 | 'indent_size': 1, |
||
55 | 'indent_char': '\t', |
||
56 | 'selector_separator': ' ', |
||
57 | 'end_with_newline': false, |
||
58 | 'newline_between_rules': true, |
||
59 | 'space_around_selector_separator': true |
||
60 | }); |
