自定义UI
- I just use this characteristics in sass: @extend, %template, @mixin, @import, and variate
- How do I name a css class? I just use '-' to separate word group, for example: button and button-group
- How do I name a modifier of a css class? I use '--' to separate the css name and modifier name, for example: button-group--vertical, button--success
- How do I name a css class which belong to another css class? I use '_' to separate the css name and its parent css class
