This time I will show you how to add rounded borders to border-radius elements, what are the precautions for adding rounded borders to border-radius elements, the following is the actual combat Let’s take a look at the case.

border-radius:10px; /* All corners are rounded with a radius of 10px*/

border-radius: 5px 4px 3px 2px; /* The four radius values are the upper left Corner, upper right corner, lower right corner and lower left corner, clockwise*/

Don’t think that the value of border-radius can only be in px units. You can also use percentages or ems, but the compatibility is not very good yet. .

Solid upper semicircle:

Method: Set the height (height) to half the width (width), and only set the radius of the upper left corner and upper right corner to be consistent with the height of the element (greater than also OK).

div{   
　　height:50px;/*是width的一半*/   
　　width:100px;   
　　background:#9da;   
　　border-radius:50px 50px 0 0;/*半径至少设置为height的值*/   
　　}
