How does vue get the child elements of the current element to perform the animation defined above?

{{notice}}

  // 
  overScroll ($event) {
    let _this = this
    clearInterval(window.intervalScroll)
    // animatetxtcss3
    //$event.target.children[1]._this.animateTxt= true
  },
  // 
  outScroll () {
    window.intervalScroll = setInterval(this.scroll, 2500)
  },

.animTxt {

transition: all 1.1s;
margin-left: -500px;

}
