SASS安装的那些事

在几个月前,就发现SASS,当时欣喜若狂,一直没有时间进行学习,现在可以好好的学习,记下笔记。可以说SASS在css的基础上进行补充和扩展,实现模块化和编程化开发,能快速,有效的构建项目,实现代码的可重用率和可读性,让sass具有变量,函数,面向对象,引用,计算等特性。

SASS安装

安装很简单,坑的是出现莫名其妙的的错误

普通安装方法

SASS的安装需ruby环境支持,下载ruby安装完后,打开Start Command Prompt with Ruby

SASS安装的那些事

然后在命令行中输入

gem install sass

安装完后,查看版本号,输入

sass -v

需要查看帮助命令,输入

sass -h

其它安装方法

前几天晚上,我安装的时候,一直安装不上,网络应该被强了,在网上找到了淘宝RubyGems镜像安装

$ gem sources --remove https://rubygems.org/
$ gem sources -a https://ruby.taobao.org/
$ gem sources -l
*** CURRENT SOURCES *** https://ruby.taobao.org
# 请确保只有 ruby.taobao.org
$ gem install sass

只有mac下面才可以输入上面命令,在window下,需要去掉$字符,我已经被坑了几回,万恶的资本主义,在安装grunt的时候也是同样

错误解决方案

在SASS中会遇到这样和那样的错误,每解决一个错误,作为一点经验,一点点的茁壮成长

GBK中文字符编译输出错误

SASS安装的那些事

解决方法:

@charset "utf-8";

语法

SASS的使用,对于前几个月的我还是很难的选择。自从深入的学习javascript模块开发,组件开发,设计模式,css的NEC模块规范后,突然发现SASS是那么和蔼可亲的O(∩_∩)O~

文件后缀名

在SASS中,分2种格式.sass.scss,它们的写法不同,生成的代码一样。这两种的区别在于.sass文件对代码的排版有着非常严格的要求,而且没有大括号,没有分号。

//文件后缀名为sass的语法
body
background: #eee
font-size:12px
p
background: #0982c1 //文件后缀名为scss的语法
body {
background: #eee;
font-size:12px;
}
p{
background: #0982c1;
}

导入

在SASS文件中导入文件,可以这样来写

@import "base.css"; //导入base.css文件
@import "a" // 导入a.acss文件
