HTML:
<div class="main">
  <div class="inner"></div>
</div>
 CSS:
*{
  padding: 0;
  margin: 0;
}
.main{
  margin: 40px auto;
   width: 100px;
  border: 1px solid -sharp000;
}
.inner{
 width: 100px;
 height: 100px;
 background-color: pink;
/* margin-top: -10px;
 margin-top: 10px;
 margin-bottom: -10px;
 margin-bottom: 10px;
 margin-left: -10px;
 margin-left: 10px;
margin-right: -10px;
margin-right: 10px;*/
}
in the above inner comments, the positive and negative values of margin-top, margin-bottom and margin-left all have an effect, but the positive and negative values of margin-right do not reflect. Why? And is the point of setting negative values just for movement?
