sublime格式化插件---HTML-CSS-JS Prettify美化代码
1.HTML-CSS-JS Prettify
HTML-CSSS-JS Prettify插件使用js-beautify来格式化js、html与css代码。
可以在这里尝试js-beautify的效果
原始代码：
// This is just a sample script. Paste your real code (javascript or HTML) here.
if (‘this_is‘==/an_example/){of_beautifier();}else{var a=b?(c%d):e[f];}格式化后的代码：
// This is just a sample script. Paste your real code (javascript or HTML) here.
if (‘this_is‘ == /an_example/) {
of_beautifier();
} else {
var a = b ? (c % d) : e[f];
}有了这个，个人认为在前端开发中，可以不用Alignment和JsFormat这两个插件。
Alignment的代码对齐HTML-CSS-JS Prettify也有，JsFormat实际上也用的是js-beautify。
如果只是针对html、css与js代码，HTML-CSS-JS Prettify就够了
1.1HTML-CSS-JS Prettify安装
HTML-CSSS-JS Prettify插件使用的是node版的js-beautify，因此需要首先安装node，node的安装请自行搜索。
在node安装完成后，使用npm安装js-beautify，命令 npm install -g js-beautify
HTML-CSS-JS Prettify的安装推荐使用PackageControl
Ctrl+Shift+P输入Install Package，然后输入HTML-CSS-JS Prettify进行安装
1.2.HTML-CSS-JS Prettify配置
HTML-CSS-JS Prettify配置可使用.jsbeautifyrc文件，js-beautify会在被优化代码文件的当前目录查找，如果找不到会向上级目录查找。
因此，可以在项目的根目录新建.jsbeautifyrc文件来配置js-beautify
贴一下我的配置，是从这里扣下来的,改的比较少

}
}主要的改动就是
修改了"html"的"allowed_file_extensions"，增加了aspx和jsp的支持
修改了"css"的"selector_separator_newline"，个人觉得没必要每个选择器都要占一行
修改了"js"的"allowed_file_extensions"，增加了.csslintrc文件的支持
修改了"html"、"css"、"js"的"indent_size"，我的代码缩进为2个空格
1.3.HTML-CSS-JS Prettify使用
使用Ctrl+Shift+H，优化当前代码文件。
使用js文件测试一下，优化前
优化后
js-beautify对css的格式化，有个问题是，会在注释下面插入一行空白字符
如下图，优化前
