question: How to achieve a rounded rectangle through p+css and positioning?

Solution overview:

Content: First add a large layer inside the tag (the large layer is used to fix the overall frame), and then the large layer contains four small layers (place four rounded corners in each of the four small layers (use ps to make an oval shape in advance, and then use the slice tool to cut the picture))

Style: Attributes that the css set inside the <head> tag must have:

1.position : relative;

2. Width and height;

3 Background color;

4. Border line (used to adjust the relative position of the four original corners. After adjustment You can delete the border line setting)

When setting the css of a small layer, the attributes that must be present in each layer are:

1.position: absolute;

2. Width and height;

3. Direction attribute (left, right, bottom,top)

4.background: url("")no-repeat;(Introducing rounded corner pictures in all directions)

The following is my code to implement a rounded rectangle:
