<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>c3扇形</title> <style> .sector{ width: 0; height: 0; border-width: 50px; border-style: solid; border-color: #f00 transparent transparent; border-radius: 50px } </style> </head> <body> <div class="sector"></div> </body> </html>
