in order to have the white cut out circle transparent and let the background show through it, you can use box-shadows
on 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-color
property.
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:
<div></div>
CSS:
CSS:
div {
width: 250px;
height: 250px;
margin: 10px;
background: #448CCB;
}
div:before {
content:" ";
background:white;
display: block;
width:250px;
height: 125px;
border-radius: 0 0 125px 125px;
}
