    <div class="img2" style="background-image: url(./img/car2.jpeg);"></div>
  </div>
  <div class="indicator"></div>
</div>

.slider {
  width: 700px;
  height: 400px;
  overflow: hidden;
  position: relative;
}

.slider-wrapper {
  width: 1400px;
  height: 400px;
  position: relative;
  left: 50%;
  transform: translateX(-50%);
}

.slider-wrapper div {
  width: 700px;
  height: 400px;
  float: left;
}

.indicator {
  height: 100%;
  width: 2px;
  background-color: #fff;
  position: absolute;
  top: 0;
  left: 350px;
