0x001 特效演示

This is fires
This is lines
This is hearts
This is bubbles
This is confetti
This is sunbeams

0x002 Fires 特效

1. JS 代码

<script>
function fire() { 
   $.each($(".particletext.fire"), function(){ 
      var firecount = ($(this).width()/50)*20; 
      for(var i = 0; i <= firecount; i++) { 
         var size = $.rnd(8,12); 
         $(this).append('<span class="particle" style="top:' + $.rnd(40,70) + '%; left:' + $.rnd(-10,100) + '%;width:' + size + 'px; height:' + size + 'px;animation-delay: ' + ($.rnd(0,20)/10) + 's;"></span>'); 
      } 
   }); 
} 
  jQuery.rnd = function(m,n) {
      m = parseInt(m);
      n = parseInt(n);
      return Math.floor( Math.random() * (n - m + 1) ) + m;
  }
  fire();
</script>

2. CSS 代码

<style>
.fire > .particle {
  position: absolute;
  background-color: rgba(255, 193, 7, 0.5);

          animation: fires 0.8s linear infinite;
  -webkit-transform: rotate(-45deg);
          transform: rotate(-45deg);
  opacity: 0;
}

@-webkit-keyframes fires {
  0% {
    -webkit-transform: rotate(-70deg) translateY(0%);
