CSS layout skills: best practices for achieving full-screen scrolling effect

In modern web design, full-screen scrolling effect has become a very popular page interaction method. Through full-screen scrolling, web content can be switched on a page-by-page basis, giving users a smoother and visually rich experience. This article will introduce some CSS layout techniques to help developers achieve best practices for full-screen scrolling effects.

1. HTML layout structure
   Before realizing the full-screen scrolling effect, you first need to build a basic HTML structure. Generally speaking, you can use a main container to wrap all screens and display page content in a split-screen manner. Each screen can be represented by a section element, for example:

<div class="main-container">
  <section class="section section-1">
    <!-- 第一个屏幕的内容 -->
  </section>
  <section class="section section-2">
    <!-- 第二个屏幕的内容 -->
  </section>
  <!-- 更多屏幕... -->
</div>

2. CSS style settings
   In order to achieve the full-screen scrolling effect, some style settings need to be performed on the page elements. First, set the main container to fill the entire screen and disable scrolling:

.main-container {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  overflow: hidden;
}

Next, set each section element to fill the entire screen and stack them vertically using absolute positioning Together:

.section {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

3. JavaScript interaction
   In order to achieve the effect of scrolling to switch pages, JavaScript needs to be used to listen to the user's scrolling events and change the position of the page accordingly. The following is a basic sample code:

document.addEventListener('wheel', function(event) {
  event.preventDefault(); // 阻止默认滚动行为
  
  var delta = event.deltaY;
  var scrollSpeed = 1000; // 滚动速度，可根据需求调整
  
  // 计算下一个要滚动到的位置
  var scrollPosition = window.pageYOffset + delta * scrollSpeed;
  
  // 滚动动画
  window.scrollTo({
    top: scrollPosition,
    behavior: 'smooth'
  });
});

In the above code, we listen to the wheel event (wheel scroll event) and prevent the default scrolling behavior. Based on the direction and speed of scrolling, calculate the next position to scroll to, and use the window.scrollTo method to perform scrolling animation.

4. Other optimization techniques
   In order to achieve a better user experience, you can consider some other optimization techniques. For example, you can add transition effects, animation effects, background images, etc. to increase the dynamics and beauty of the page. In addition, you can use the deltaY attribute of the mouse wheel event to determine the direction of scrolling, thereby achieving switching effects in different directions.

Summary:
Through the above CSS layout techniques and JavaScript interaction, we can achieve a web page with a full-screen scrolling effect. Through reasonable layout structure and style settings, combined with moderate JavaScript interaction, users can be provided with a smooth and visually rich page experience. Of course, in actual development, it can also be flexibly adjusted and optimized according to specific needs.
