部分CSS:

  position: fixed;
  top: 30%;

  width: 100%;
  text-align: center;
  transform:translateY(-50%);
  font-family: 'Love Ya Like A Sister', cursive;
  font-size: 60px;
  color: #c70012;
  padding: 0 20px;
}
h1 span{
  position: fixed;

</style>

部分JS:

  this.opacity = 1;
  this.vertices = [];
  for (var i = 0; i < precision; i++) {
    var step = (i / precision - 0.5) * (Math.PI * 2);
    var vector = {
      x : (15 * Math.pow(Math.sin(step), 3)),
      y : -(13 * Math.cos(step) - 5 * Math.cos(2 * step) - 2 * Math.cos(3 * step) - Math.cos(4 * step))

}

  ctx.save();
  ctx.translate(-1000,this.y);
  ctx.scale(this.size, this.size);

  }
  ctx.globalAlpha = this.size;

  ctx.closePath();
  ctx.fill()
  ctx.restore();
};


function render(a){
  requestAnimationFrame(render);

  hearts.push(new Heart())
  ctx.clearRect(0,0,ww,wh);
  for (var i = 0; i < hearts.length; i++) {
    hearts[i].draw();
    if(hearts[i].size <= 0){
      hearts.splice(i,1);
      i--;
    }
