这段代码需要配合一定的 CSS 样式才能正常显示轮播图效果，以下是一个简单的 CSS 样式示例：

.slidershow {
  width: 100%;
  position: relative;
  overflow: hidden;
}

.slides {
  display: flex;
  width: 100%;
}

.slide {
  flex-shrink: 0;
  width: 100%;
  transition: opacity 1s ease;
  opacity: 0;
  position: absolute;
  top: 0;
  left: 0;
}

.slide:first-child {
  opacity: 1;
}

.navigation {
  position: absolute;
  bottom: 10px;
  left: 50%;
  transform: translateX(-50%);
  display: flex;
}

.bar {
  width: 15px;
  height: 15px;
  margin: 0 5px;
  border-radius: 50%;
  background-color: #fff;
  cursor: pointer;
  transition: transform 0.2s ease;
}

input[type="radio"]:checked + .bar {
  transform: scale(1.5);
}

.s1 {
  z-index: 1;
}

#r1:checked ~ .s1,
#r2:checked ~ .s2,
#r3:checked ~ .s3,
#r4:checked ~ .s4 {
  opacity: 1;
  z-index: 2;
}

注意在 HTML 中需要引入上述的 CSS 样式文件。
