Generally speaking, CSS-based rounded corner technology is divided into two categories: with pictures and without pictures. Among them, there are those who use JavaScript and those who do not use JavaScript. So each has its own advantages and disadvantages. Also, some of the processed fillets are jagged, and some people even use the sawtooth to make rounded corners, so some people challenge to make jagged corners. In short, new technologies are constantly emerging, and new comrades challenge old comrades. Just this CSS rounded corner technology is exciting enough.
The general structure of rounded corners using pictures is relatively simple, while those that do not use pictures are often layers of divs that are nested together. Using JavaScript on a page can sometimes be unflattering. Therefore, I hope to find a method that does not require images, does not require JavaScript, and has a simple structure. If possible, it is best to eliminate aliasing (nonsense!).
