使用 CSS-HTML 的幻灯片仅显示四张幻灯片

Question

我正在使用幻灯片，我只使用 css 和 HTML。我总共使用了六张幻灯片，但它只显示了四张幻灯片。它不会移动到第 5 位和第 6 位。我不明白我在哪里犯了错误，请纠正我。

你可以在 JsFiddle 上看到我面临的问题。希望你帮忙，提前致谢。

#slideshow {
  overflow: hidden;
  height: 510px;
  width: 728px;
  margin: 0 auto;
}

.slide-wrapper {
  width: 4368px; /*change this width */
  -webkit-animation: slide 10s ease infinite;
}

.slide {
  float: left;
  height: 510px;
  width: 728px;
}

.slide:nth-child(1) {
  background: #D93B65;
}

.slide:nth-child(2) {
  background: #037E8C;
}

.slide:nth-child(3) {
  background: #36BF66;
}

.slide:nth-child(4) {
  background: #D9D055;
}

.slide:nth-child(5) {
  background: #D9D055;
}

.slide:nth-child(6) {
  background: #D9D055;
}

.slide-number {
  color: #000;
  text-align: center;
  font-size: 10em;
}

@-webkit-keyframes slide {  /* add keyframe animations to move each slide towards left */
  15% {margin-left: 0px;}
  30% {margin-left: -728px;}
  45% {margin-left: -1456px;}
  60% {margin-left: -2184px;}
  75%{margin-left: -2912px;}
  90%{margin-left: -3640px;}

}
