css - CSS阴影改变侧

Question

-moz-box-shadow: inset 3px 3px rgba(0,0,0,0.5);
-webkit-box-shadow: inset 3px 3px rgba(0,0,0,0.5);
box-shadow: inset 3px 3px rgba(0,0,0,0.5);

这会在顶部和左侧生成一个嵌入阴影。我不知道要让它在底部和右侧！

Answer 1

使位置值为负：

-moz-box-shadow: inset -3px -3px rgba(0,0,0,0.5);
-webkit-box-shadow: inset -3px -3px rgba(0,0,0,0.5);
box-shadow: inset -3px -3px rgba(0,0,0,0.5);
