JS

Потребуется библиотека anime.js

и сам скрипт

    var pad = padding || 0;
    var parentEl = el.parentNode;
    var elOffsetWidth = el.offsetWidth - pad;
    var parentOffsetWidth = parentEl.offsetWidth;
    var ratio = parentOffsetWidth / elOffsetWidth;
    timeout = setTimeout(anime.set(el, {scale: ratio}), 10);
  }
  resize();
  window.addEventListener('resize', resize);
}

var sphereAnimation = (function() {

  var sphereEl = document.querySelector('.sphere-animation');

          stroke: {value: ['rgba(255,75,75,1)', 'rgba(80,80,80,.35)'], duration: 500},
          translateX: [2, -4],

        var percent = (1 - Math.sin((i * .35) + (.0022 * ins.currentTime))) / 2;
        animation.seek(animation.duration * percent);
      });
    },
    duration: Infinity,
    autoplay: false
  });

  var introAnimation = anime.timeline({
    autoplay: false
  })
  .add({

    },
    duration: 2000,
    delay: anime.stagger(60, {direction: 'reverse'}),
    easing: 'linear'
  }, 0);

  var shadowAnimation = anime({
      targets: '#sphereGradient',
      x1: '25%',
      x2: '25%',
      y1: '0%',
      y2: '75%',
      duration: 30000,
      easing: 'easeOutQuint',
      autoplay: false
    }, 0);

  function init() {
