写了一段时间的代码,总觉得自己的代码还是有点乱,看着很不舒服,所以现在开始规范自己的代码书写,先从CSS样式表的书写开始。
下面的内容内容参照了许多网友的例子,小编总结如下:
1.命名规则说明
- 规则命名中,一律采用小写加中划线的方式,不允许使用大写字母或 _ ;
- 命名避免使用中文拼音,应该采用更简明有语义的英文单词进行组合;
- 不允许通过1、2、3等序号进行命名 相信也不会有人这样命名;
-
id用于标识模块或页面的某一个父容器区域,名称必须唯一,不要随意新建id ;
不要随意使用ID
class用于标识某一个类型的对象,命名必须言简意赅;
- 尽可能提高代码模块的复用,样式尽量用组合的方式样式的复用这里可以写一个公共的样式;
- 规则名称中不应该包含颜色(red/blue)、定位(left/right)等与具体显示效果相关的信息。应该用意义命名,而不是样式显示结果命名;
- 有时候可以给选择器添加一个表示状态的前缀,全语义更明了,比如下图是添加了“.is-”前缀。
2.CSS主要文件命名
文件类型 | 命名 |
---|---|
主要的 | master.css /style.css |
模块 | module.css |
基本公用 | base.css |
布局,版面 | layout.css |
专栏 | columns.css |
文字 | font.css |
表单 | forms.css |
打印样式 | print.css |
主题 | themes.css |
补丁 | mend.css |
3.常用ID的命名
页面结构结构类型 | 命名 |
---|---|
页面外围控制整体布局宽度 | wrapper |
容器 | container |
页头 | header |
内容 | content/container |
页面主体 | main |
页尾 | footer |
导航 | nav |
侧栏 | sidebar |
左中右 | _l, _c, _r |
栏目 | column |
导航类型 | 命名 |
---|---|
导航 | nav |
主导航 | mainbav |
子导航 | subnav |
顶导航 | topnav |
边导航 | sidebar |
左导航 | leftsidebar |
右导航 | rightsidebar |
菜单 | menu |
子菜单 | submenu |
标题 | title |
摘要 | summary |
功能类型 | 命名 | 功能类型 | 命名 |
---|---|---|---|
标志 | logo | 当前的 | current |
广告 | banner | 小技巧 | tips |
登陆 | login | 图标 | icon |
登录条 | loginbar | 注释 | note |
注册 | regsiter | 指南 | guild |
搜索 | search | 服务 | service |
功能区 | shop | 热点 | hot |
标题 | title | 新闻 | news |
加入 | joinus | 下载 | download |
状态 | status | 投票 | vote |
按钮 | btn | 合作伙伴 | partner |
滚动 | scroll | 友情链接 | link |
标签页 | tab | 版权 | copyright |
文章列表 | list | 提示信息 | msg |
指南 | guid | 网站地图 | sitemap |
3.CSS属性编写顺序
- 显示属性:display/list-style/position/float/clear …
- 自身属性(盒模型):width/height/margin/padding/border
- 背景:background
- 行高:line-height
- 文本属性:color/font/text-decoration/text-align/text-indent/vertical-align/white-space/content…
- 其他:cursor/z-index/zoom/overflow
- CSS3属性:transform/transition/animation/box-shadow/border-radius
- 如果使用CSS3的属性,如果有必要加入浏览器前缀,则按照 -webkit- / -moz- / -ms- / -o- / std的顺序进行添加,标准属性写在最后。
- 链接的样式请严格按照如下顺序添加: a:link -> a:visited -> a:hover -> a:active
4.代码优化
好的代码必须要做到优化、精简。多余的代码将会给后期的编程带来更多的不便和资源的浪费。
CSS有些属性是可以缩写的,比如padding,margin,font等等,这样精简代码同时又能提高用户的阅读体验。去掉小数点前的“0”
简写命名
很多用户都喜欢简写类名,但前提是要让人看懂你的命名才能简写哦!
16进制颜色代码缩写
有些颜色代码是可以缩写的,我们就尽量缩写吧,提高用户体验为主。
5.注释规范
这个一定要和html文件的注释和顺序一致,这样有助于后期代码的查找和改动。
/* Header */内容区/* End Header */
6.css hack 的使用
请不用动不动就使用浏览器检测和CSS Hacks,先试试别的解决方法吧!考虑到代码高效率和易管理,虽然这两种方法能快速解决浏览器解析差异,但应被视为最后的手段。在长期的项目中,允许使用hack只会带来更多的hack,你越是使用它,你越是会依赖它!
不得不用的时候推荐使用下面的这些:
IE6 | _property:value |
IE6/7 | *property:value |
IE6/7/8/9 | _property:value\9 |
基本总结的也差不多了,如有漏掉的,大家提个意见,我再补上^_^
