CSS 父级子级

什么是CSS父级子级?

目录
  1. 认识理解
  2. 举例
  3. 父级子级目的

1、认识了解 -  TOP

简单讲CSS父级 CSS子级是相对而言,如一个DIVCSS5学习网 “A”被另外一个DIV “B”包裹着,这样我们就可以认为B是A父级,同样一个道理。

父级子级或有时把DIV嵌套关系比作父亲儿子关系,这个是为了便于理解将DIV嵌套关系形象比作父级子级关系叫法。

2、举例说明: -  TOP

DIVCSS5学习网 父级子级说明例子:
CSS代码

  1. .yangshi{...} 
  2. .yangshi .yangshi_a{ ...} 
  3. .yangshi .yangshi_b{ ...} 

Div代码

  1. <div class="yangshi"> 
  2. <div class="yangshi_a">内容a</div> 
  3. <div class="yangshi_b">内容b</div> 
  4. </div> 

以上DIVCSS5学习网代码这里我们就可以认为 yangshi_a父级(上一级)是yangshi。
这样我们就可以利用CSS指针属性在div css中,最终CSS样式可以有相同命名的属性选择器的,但是赋予不同的值。
这样我们通过.yangshi .yangshi_a一看即可知道yangshi_a的父级是yangshi

3、认识CSS父级子级目的: -  TOP

我们搞清div css之间父级自己关系,目的也是为我们维护和查找。
