基于HTML，CSS & Javascript 实现图像的自动轮播和手动导航按钮

不务正业的第n天（划掉

2020年年末在完成Web网页制作课程的大作战，在写代码的时候想到用HTML + CSS & Javascript制作一个图片轮播功能增强网页的功能

简单贴一下代码：注释用了简单的英文，应该都能看懂

HTML

<!DOCTYPE html>
<html lang="en" dir="ltr">

<head>
  <meta charset="utf-8">
  <title>Image Slider</title>
  <link rel="stylesheet" href="style.css">
</head>

<body>

  <!--image slider start-->
  <div class="slider">
    <div class="slides">
      <!--radio buttons start-->
      <input type="radio" name="radio-btn" id="radio1">
      <input type="radio" name="radio-btn" id="radio2">
      <input type="radio" name="radio-btn" id="radio3">
      <input type="radio" name="radio-btn" id="radio4">
      <!--radio buttons end-->
      <!--slide images start-->
      <div class="slide first">
        <img src="1.jpg" alt="">
      </div>
      <div class="slide">
        <img src="2.jpg" alt="">
      </div>
      <div class="slide">
        <img src="3.jpg" alt="">
      </div>
      <div class="slide">
        <img src="4.jpg" alt="">
      </div>
      <!--slide images end-->
      <!--automatic navigation start-->
      <div class="navigation-auto">
        <div class="auto-btn1"></div>
        <div class="auto-btn2"></div>
        <div class="auto-btn3"></div>
        <div class="auto-btn4"></div>
      </div>
      <!--automatic navigation end-->
    </div>
    <!--manual navigation start-->
    <div class="navigation-manual">
      <label for="radio1" class="manual-btn"></label>
      <label for="radio2" class="manual-btn"></label>
      <label for="radio3" class="manual-btn"></label>
      <label for="radio4" class="manual-btn"></label>
    </div>
    <!--manual navigation end-->
  </div>
  <!--image slider end-->

  <script type="text/javascript">
    var counter = 1;
    setInterval(function () {
      document.getElementById('radio' + counter).checked = true;
      counter++;
      if (counter > 4) {
        counter = 1;
      }
    }, 5000);
  </script>

</body>

</html>

CSS

body {
  margin: 0;
  padding: 0;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  background: #23E3C9;
}

.slider {
  width: 800px;
  height: 500px;
  border-radius: 10px;
  overflow: hidden;
}

.slides {
  width: 500%;
  height: 500px;
  display: flex;
}

.slides input {
  display: none;
}

.slide {
  width: 20%;
  transition: 2s;
}

.slide img {
  width: 800px;
  height: 500px;
}

/*css for manual slide navigation*/

.navigation-manual {
  position: absolute;
  width: 800px;
  margin-top: -40px;
  display: flex;
  justify-content: center;
}

.manual-btn {
  border: 2px solid #40D3DC;
  padding: 5px;
  border-radius: 10px;
  cursor: pointer;
  transition: 1s;
}

.manual-btn:not(:last-child) {
  margin-right: 40px;
}

.manual-btn:hover {
  background: #40D3DC;
}

#radio1:checked~.first {
  margin-left: 0;
}

#radio2:checked~.first {
  margin-left: -20%;
}

#radio3:checked~.first {
  margin-left: -40%;
}

#radio4:checked~.first {
  margin-left: -60%;
}

/*css for automatic navigation*/

.navigation-auto {
  position: absolute;
  display: flex;
  width: 800px;
  justify-content: center;
  margin-top: 460px;
}

.navigation-auto div {
  border: 2px solid #40D3DC;
  padding: 5px;
  border-radius: 10px;
  transition: 1s;
}

.navigation-auto div:not(:last-child) {
  margin-right: 40px;
}

#radio1:checked~.navigation-auto .auto-btn1 {
  background: #40D3DC;
}

#radio2:checked~.navigation-auto .auto-btn2 {
  background: #40D3DC;
}

#radio3:checked~.navigation-auto .auto-btn3 {
  background: #40D3DC;
}

#radio4:checked~.navigation-auto .auto-btn4 {
  background: #40D3DC;
}

关于这个页面的改进点，可以在切换不同图片的时候自动切换背景图颜色来搭配图片。

这里只要改一下Javascript 和 CSS 的代码即可
