How to create a slide layout page using HTML and CSS

Introduction:
Slide layout is widely used in modern web design, when displaying information or Pictures are very engaging and interactive. This article will introduce how to create a slide layout page using HTML and CSS, and provide specific code examples.

1. HTML layout structure
First, we need to create an HTML layout structure, including a slide container and multiple slide items. The code is as follows:

<!DOCTYPE html>
<html>
<head>
  <title>幻灯片布局页面</title>
  <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
  <div class="slider-container">
    <div class="slider-item">
      <img src="image1.jpg" alt="Slide 1">
    </div>
    <div class="slider-item">
      <img src="image2.jpg" alt="Slide 2">
    </div>
    <div class="slider-item">
      <img src="image3.jpg" alt="Slide 3">
    </div>
  </div>
</body>
</html>

In the above code, .slider-container is the class name of the slide container, .slider-item is each slide The class name of the item. You can add or reduce slide items as needed.

2. CSS style setting
Next, we need to use CSS to set the style of the slide layout. The code is as follows:

.slider-container {
  width: 500px;
  height: 300px;
  overflow: hidden;
  position: relative;
}

.slider-item {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 100%;
  transition: left 0.5s;
}

.slider-item.active {
  left: 0;
}

.slider-item img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}

In the above code, we set the width, height and overflow hiding of the slide container. Each slide item uses absolute positioning, the initial state is off-screen, and the left attribute is used for movement animation. Identify the currently active slide item by adding the .active class.

3. JavaScript interaction
In order to realize the automatic playback and loop switching functions of the slideshow, we also need to use JavaScript to add interaction. The code looks like this:

<script>
  var slideIndex = 0;
  showSlides();

  function showSlides() {
    var slides = document.getElementsByClassName("slider-item");
    for (var i = 0; i < slides.length; i++) {
      slides[i].classList.remove("active");
    }
    slideIndex++;
    if (slideIndex > slides.length) {
      slideIndex = 1;
    }
    slides[slideIndex - 1].classList.add("active");
    setTimeout(showSlides, 3000);
  }
</script>

Copy after login

In the above code, we define a slideIndex variable to track the index of the slide. Use the showSlides function to iterate the slide items and add and delete the .active class to achieve the carousel effect. Use the setTimeout function to set the slide automatic playback interval, here it is 3 seconds.

Conclusion:
With the above HTML, CSS and JavaScript code examples, we can create a simple slide layout page and implement automatic playback and loop switching functions. You can also further expand and optimize this layout according to your needs. The flexibility and display effect of slide layout add dynamics and vitality to the visual effect of the web page.
