sass是一种css的开发工具,并且是一款基于ruby的开发工具,因此想要使用这个工具必须先安装ruby。sass提供两种后缀格式的文件:.scss和.sass。区别是,scss彻底兼容css格式,而sass则必须遵照严格的缩进而且不使用{}css
.scss文件web
.container { .content { margin: 10px; } }
编译sass
suntopo@suntopo-X550VX:~/Desktop$ sass test.scss .container .content { margin: 10px; } suntopo@suntopo-X550VX:~/Desktop$
在不指定任何参数状况下,sass默认输出到终端ruby
指定目标路径工具
suntopo@suntopo-X550VX:~/Desktop$ sass test.scss ./test.css
将生成test.css和test.css.map两个文件开发工具
指定输出格式ui
sass中有四种css的输出格式:nested(默认),apended(没有缩进),compact(简洁),compressed(压缩)google
suntopo@suntopo-X550VX:~/Desktop$ sass --style compressed test.scss .container .content{margin:10px}
文件监控code
若是每次修改都手动编译很不方便,sass也提供了文件监控功能实现修改后自动编译orm
suntopo@suntopo-X550VX:~/Desktop$ sass --watch test.scss:test.css >>> Sass is watching for changes. Press Ctrl-C to stop. write test.css write test.css.map
sass自己只是一个编译器,而compass是在它基础只是进一步的封装。封装了一系列有用的模块和模板,是对sass的补充。
建立
suntopo@suntopo-X550VX:~/Desktop$ compass create test directory test/ directory test/sass/ directory test/stylesheets/ create test/config.rb create test/sass/screen.scss create test/sass/print.scss create test/sass/ie.scss write test/stylesheets/ie.css write test/stylesheets/print.css write test/stylesheets/screen.css ********************************************************************* Congratulations! Your compass project has been created. You may now add and edit sass stylesheets in the sass subdirectory of your project. Sass files beginning with an underscore are called partials and won't be compiled to CSS, but they can be imported into other sass stylesheets. You can configure your project by editing the config.rb configuration file. You must compile your sass stylesheets into CSS when they change. This can be done in one of the following ways: 1. To compile on demand: compass compile [path/to/project] 2. To monitor your project for changes and automatically recompile: compass watch [path/to/project] More Resources: * Website: http://compass-style.org/ * Sass: http://sass-lang.com * Community: http://groups.google.com/group/compass-users/ To import your new stylesheets add the following lines of HTML (or equivalent) to your webpage: <head> <link href="/stylesheets/screen.css" media="screen, projection" rel="stylesheet" type="text/css" /> <link href="/stylesheets/print.css" media="print" rel="stylesheet" type="text/css" /> <!--[if IE]> <link href="/stylesheets/ie.css" media="screen, projection" rel="stylesheet" type="text/css" /> <![endif]--> </head>
介绍的很清楚,就很少说
