You can also set two values ??border-radius at the same time: 50px 99px; correspondingly, they are 50px for top and bottom, and 99px for left and right. You can also set three values ??to set the border-radius clockwise: 50px 99px 40px; the top is 50px, the left and right are 99px, and the bottom is 40px. <\/p>
2. You can also use border-radius: r to set a circle. The r here refers to the size of the radius (with a length unit). To create a circle, you should set the value of r to the height of the element. and half the length. When the height and width are equal, this method of selecting the value is that the circle will develop towards an ellipse as the width and height are changed. <\/strong><\/p>\n\n\n \n
