目录规范
直接置于${root}下的目录称作一级目录。一级目录 必须(MUST) 具有某种职能属性。 除了下面列举的一些常见目录之外，${root}下面也可以放置一些跟项目发布相关的文件，例如build.sh，build.xml，Makefile，Gruntfile等等.
一级目录
- src
- dep
- tool
- test
- doc
- entry
- assets
资源目录
tpl
模块和加载器规范
建议使用AMD规范
部分参数注意
命名规则
小写＋下划线
目录复数
HTML
soft tab
自动闭合标签不使用/
属性出现顺序
- class
- id
- name
- data-*
- src, for, type, href, value , max-length, max, min, pattern
- placeholder, title, alt
- aria-*, role
- required, readonly, disabled
尽量减少标签数量
CSS, SCSS
soft tab
注释统一使用/* */
类名BEM命名法，id驼峰命名
scss驼峰命名
颜色16进制小写
尽量不要属性简写，margin, padding除外

Javascript
以下几种情况需要空行：
- 变量声明后（当变量声明在代码块的最后一行时，则无需空行）
- 注释前（当注释在代码块的第一行时，则无需空行）
- 代码块后（在函数调用、数组、对象中则无需空行）
- 文件最后保留一个空行
注释双斜线后跟一个空格// your comment
变量命名
- 标准变量采用驼峰式命名（除了对象的属性外，主要是考虑到cgi返回的数据）
- ‘ID’在变量名中全大写
- ‘URL’在变量名中全大写
- ‘Android’在变量名中大写第一个字母
- ‘iOS’在变量名中小写第一个，大写后两个字母
- 常量全大写，用下划线连接
- 构造函数，大写第一个字母
- jquery对象必须以’$’开头命名
{前一定要有空格
永远不要直接使用undefined进行变量判断；
使用typeof和字符串’undefined’对变量进行判断。
