HomeWeb Front-endHTML Tutorialhtml的块级、内联、内联块级元素基础_html/css_WEB-ITnose

概念

块级:block

内联:inline

内联块级:inline-block

 

在html元素中,元素会有display属性

display属性默认值是block,那么该元素是块级元素。

display属性默认值是inline,那么该元素是内联元素。

没有元素的display默认值是inline-block。

display属性值可以被设置,比如可以把块级元素div的display的值设成inline,那么它就变成了内联元素,不再独行显示。

 

特征

1.块级元素

  独占一行。

  可设置width,height,margin,padding。

  内部可包含块级或内联元素。

2.内联元素

  和其他inline元素同行显示。

  设置widht,height,margin-top,margin-bottom,padding-top,padding-bottom无效,可以设置margin-left,margin-righ,padding-left,padding-right。

  内部可包含块级或内联元素,内部包含块级元素时,该块级元素继续保持独行显示,下一个内联元素会换行显示。

3.inline-block

  和其他inline元素同行显示。

  和块级元素一样可设置width,height,margin,padding。

  内部可包含块级或内联元素,内部包含块级元素时,该块级元素会在内联元素的内部独行显示,不会影响下一个内联元素的同行显示。
