This is a gear animation special effect based on HTML5. We convert the physical principles of gear rotation into HTML5 code and implement the animation effect of simulated gear rotation on the web page. The biggest feature of this gear animation is that it is composed of multiple gears, which greatly increases the algorithm requirements for gear transmission. Moreover, we did not use JavaScript, but pure CSS3 to implement it.
