CSS naming rules specification

When people write css, they often encounter questions about Naming issue. With hundreds or even thousands of classes or IDs on the page, we will become more and more troubled. Therefore, it is necessary for us to organize our own set of naming conventions. Here I will talk about my own life

When everyone writes css, they often encounter naming problems. With hundreds or even thousands of classes or IDs on the page, we will become more and more troubled.

So, it is necessary for us to organize our own set of naming conventions. Here I will talk about my own naming convention.

Class-class

Class name, I usually use horizontal lines like this

.head-logo { … } /*Page header The class name of logo*/
.nav-li { … } /*The class name of the list on the navigation bar*/
.link-panel-h2 { … } /*The title of the link module*/

ID

id, I usually use camel case naming. In my understanding, camelCase naming is used exclusively for unique variables. So I often use this method to define variables in javascrpt.

#navLastLi { … } /*Get the last list of the navigation bar*/
#panelContent { … } /*The text part of the module*/
#sidebarFooter { … } /*Side Sidebar bottom module*/

So, there are many page modules, we can organize them like this

When we use scripts to dynamically transform pages, the recommended method is to modify the class name or modify the id name to modify the display style. Of course, the most commonly used method is to modify the display style. name class.

Modify the class name - naming specification

(1) Color: use the name of the color or Hexadecimal code, such as

.red { color: red; }

.f60 { color: #f60; }

.ff8600 { color: #ff8600; }

(2) Font size, directly use 'font font size' as the name, such as

.font12px { font-size: 12px; }

.font9pt {font-size: 9pt; }

(3) Alignment style, use the English name of the alignment target, such as

.left { float:left; }

.bottom { float:bottom; }

(4)标题栏样式,使用’类别+功能’的方式命名,如

根据页面分栏结构的命名

CSS代码的命名惯例一直是大家热门讨论的话题。通过分析一个流行三栏布局中的必要元素，来为大家讲解关于使用语义化方法替代结构化方法来命名CSS类的建议和指导。

CSS类命名的语义化VS结构化方式

一般而言，CSS类名的语义化声明方式应当考虑你的页面中某个相对元素的”用意”，独立于它的”定位”或确切的特性(结构化方式)。像left-bar, red-text, small-title…这些都属于结构化定义的例子。

让我们看看下面这个例子:

　　…而现在我们想把页面中的元素调换一下位置，如果你使用的是结构化方式(1)，那么你就要把所有CSS类名重新进行定义，因为它们的位置变了。在布局(3)中，我们看到元素都倒转了: right-bar 现在成了 “left-bar”，而 left-content 成了 “right-content”。如果你使用语义化方式则避免了此类问题。

　　换句话说，使用语义化方式的话，你在修改网站布局的时候可以仅仅修改相关CSS类的属性即可，而不用修改它们的类名了，如果网站的代码很庞大，这将节省大量的时间。
