EXTERNAL JAVASCRIPT

研究以下代码并获得想法，

/* external css: flickity.css */

* { box-sizing: border-box; }

body { font-family: sans-serif; }

.carousel {
  background: black;
}

.carousel-cell {
  width: 70%;
  height: 200px;
  /* flex-box, center image in cell */
  display: -webkit-box;
  display: -webkit-flex;
  display:         flex;
  -webkit-box-pack: center;
  -webkit-justify-content: center;
          justify-content: center;
  -webkit-align-items: center;
          align-items: center;
}

.carousel-cell img {
  display: block;
  max-width: 100%;
  max-height: 100%;
  /* dim unselected */
  opacity: 0.7;
  -webkit-transform: scale(0.85);
          transform: scale(0.85);
  -webkit-filter: blur(5px);
          filter: blur(5px);
  -webkit-transition: opacity 0.3s, -webkit-transform 0.3s, transform 0.3s, -webkit-filter 0.3s, filter 0.3s;
          transition: opacity 0.3s, transform 0.3s, filter 0.3s;
}

/* brighten selected image */
.carousel-cell.is-selected img {
  opacity: 1;
  -webkit-transform: scale(1);
          transform: scale(1);
  -webkit-filter: none;
          filter: none;
}

@media screen and ( min-width: 768px ) {
  .carousel-cell {
    height: 400px;
  }
}

@media screen and ( min-width: 960px ) {
  .carousel-cell {
    width: 60%;
  }
}

/* buttons, no circle */
.flickity-prev-next-button {
  width: 60px;
  height: 60px;
  background: transparent;
  opacity: 0.6;
}
.flickity-prev-next-button:hover {

  opacity: 1;
}
/* arrow color */
.flickity-prev-next-button .arrow {
  fill: white;
}
.flickity-prev-next-button.no-svg {
  color: white;
}
/* closer to edge */
.flickity-prev-next-button.previous { left: 0; }
