Introduction

Today I will share with you a very interesting pure CSS3 animation, which simulates the scene when the meteor shower falls. This animation takes advantage of some of the new features of CSS3, including the inclination of straight lines, color gradients, etc. It not only draws many meteor graphics, but also makes these pops randomly generated and slide across the sky. The effect is very good.
