padding对于元素position定位的影响:
关于padding和position的基本用法这里不多介绍了，可以参阅相关阅读。
相关阅读:
1.padding可以参阅CSS的padding用法详解一章节。
2.position可以参阅CSS的position属性一章节。
下面进入正题，介绍一下padding属性对于定位的影响。
代码实例:
实例一:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.box{ width:300px; height:150px; background-color:#CCC; padding:20px;}.inner{ width:50px; height:50px; background-color:red; position:relative; left:10px; top:20px;}</style></head><body><div class="box"> <div class="inner"></div></div></body></html>相对定位的参考对象由于是自身，所以不会受padding的影响。
实例二:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.box{ width:300px; height:150px; background-color:#CCC; padding:20px; position:relative;}.inner{ width:50px; height:50px; background-color:red; position:absolute;}</style></head><body><div class="box"> <div class="inner"></div></div></body></html>对于绝对定位，如果没有设置left或者top属性值，那么相应方位就不会忽略padding值。
实例三:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.box{ width:300px; height:150px; background-color:#CCC; padding:20px; position:relative;}.inner{ width:50px; height:50px; background-color:red; position:absolute; left:5px;}</style></head><body><div class="box"> <div class="inner"></div></div></body></html>对于绝对定位相应方位设置了left和top属性值，那么就会忽略相应方位的padding。
