1.HTML-CSS-JS Prettify
HTML-CSSS-JS Prettify插件使用js-beautify來格式化js、html與css代碼。
可以在這里嘗試js-beautify的效果
原始代碼：
// 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];} 格式化后的代碼：
// 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]; } 有了這個，個人認為在前端開發中，可以不用Alignment和JsFormat這兩個插件。
Alignment的代碼對齊HTML-CSS-JS Prettify也有，JsFormat實際上也用的是js-beautify。
如果只是針對html、css與js代碼，HTML-CSS-JS Prettify就夠了
1.1HTML-CSS-JS Prettify安裝
HTML-CSSS-JS Prettify插件使用的是node版的js-beautify，因此需要首先安裝node，node的安裝請自行搜索。
在node安裝完成后，使用npm安裝js-beautify，命令 npm install -g js-beautify
HTML-CSS-JS Prettify的安裝推薦使用PackageControl
Ctrl+Shift+P輸入Install Package，然后輸入HTML-CSS-JS Prettify進行安裝
1.2.HTML-CSS-JS Prettify配置
HTML-CSS-JS Prettify配置可使用.jsbeautifyrc文件，js-beautify會在被優化代碼文件的當前目錄查找，如果找不到會向上級目錄查找。
因此，可以在項目的根目錄新建.jsbeautifyrc文件來配置js-beautify
貼一下我的配置，是從這里扣下來的,改的比較少

-
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"，個人覺得沒必要每個選擇器都要占一行
-
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"，我的代碼縮進為2個空格
1.3.HTML-CSS-JS Prettify使用
使用Ctrl+Shift+H，優化當前代碼文件。
使用js文件測試一下，優化前
優化后
js-beautify對css的格式化，有個問題是，會在注釋下面插入一行空白字符
如下圖，優化前
優化后
sublime text 3 插件：HTML-CSS-JS Prettify文中給出了解決方法，大家可以參考
