in order to have the white cut out circle transparent and let the background show through it, you can use box-shadowson a pseudo element to minimize markup.

为了让白色切出的圆圈透明并让背景通过它显示,您可以使用box-shadows伪元素来最小化标记。

In the following demo, the blue color of the shape is set with the box shadow and not the background-colorproperty.

在下面的演示中,形状的蓝色是使用框阴影而不是background-color属性设置的。

If you don't mind that the "eaten" bit is white and not transparent, yes:

如果您不介意“被吃掉”的部分是白色且不透明,可以:
