html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。
