如果使用 `background-clip` 的值設(shè)置成 `content-box`，該如何處理？

.div-box{
			width:?200px;
			height:?200px;
			float:?left;
			padding:?10px;
			border:?3px?solid?red;
			margin:?3px;
			position:?relative;
			overflow:?hidden;
			background-color:?rgba(0,0,0,0.3);
		}

How do I change the margin color on CSS?

Margin, as such, doesn't have background color.?

Margin is invisible border, a space between two objects.

padding元素是補(bǔ)白哦，就是一片空白用來(lái)占用一片空間而已，可以用padding-top;padding-bottom;padding-lift;padding-right;來(lái)控制上下左右的留白空間
