CSS3 realizes the animation effect of lotus blooming

Let’s look at the effect first:

This effect looks quite dazzling, but the principle is not complicated. If one petal can be moved, then all nine petals can be made. It's just a superposition of effects.

HTML:

<section class="demo">  
  <div class="box">  
     <div class="leaf"></div>  
     <div class="leaf"></div>  
     <div class="leaf"></div>  
     <div class="leaf"></div>  
     <div class="leaf"></div>  
     <div class="leaf"></div> 
     <div class="leaf"></div>  
     <div class="leaf"></div>  
     <div class="leaf"></div>  
  </div>  
</section>
