How to use CSS to create a seamless scrolling text display effect and the steps to achieve it

In web design, the seamless scrolling text display effect brings people more Smooth and engaging user experience. This effect is usually used in scenes such as carousels and scrolling news. This article will introduce specific steps to use CSS to achieve seamless scrolling text display effects, and provide relevant code examples.

Step 1: Create HTML structure

First, we need to create a container element that contains scrolling text. Can be a div, ul or other HTML element. For example, we create a div element and give it a unique ID:

<div id="scrolling-text">
  <ul>
    <li>文字1</li>
    <li>文字2</li>
    <li>文字3</li>
    <li>文字4</li>
    <li>文字5</li>
  </ul>
</div>

Step 2: Set the style

Next, we need to set the style of the container element, including width, height, Overflow handling, etc. At the same time, you also need to set the style of each scroll item, including width, height, row height, etc. The following is a basic style setting:

#scrolling-text {
  width: 300px;
  height: 200px;
  overflow: hidden;
  position: relative;
}

#scrolling-text ul {
  list-style: none;
  margin: 0;
  padding: 0;
  position: absolute;
  animation: scrolling 10s linear infinite;
}

#scrolling-text ul li {
  width: 300px;
  height: 40px;
  line-height: 40px;
}

Step 3: Achieve seamless scrolling effect

Now, we need to use CSS animation to achieve the seamless scrolling effect of text. We can use the @keyframes rule to define an animation called scrolling and apply it to the scrolling ul element:

@keyframes scrolling {
  0% {
    top: 0;
  }
  100% {
    top: -200px;
  }
}

In the above code, we use the keyframes 0% and 100% to define respectively The starting and ending states of the animation. The top attribute controls the vertical position of the scroll item.

Step 4: Optimize the experience

In order to improve the readability and user experience of the scrolling effect, we can add mouse events to the container element to pause scrolling when the mouse hovers and when the mouse leaves Start scrolling again. Here is a sample code implemented using JavaScript:

var scrollingText = document.getElementById('scrolling-text');

scrollingText.onmouseenter = function() {
  scrollingText.style.animationPlayState = 'paused';
}

scrollingText.onmouseleave = function() {
  scrollingText.style.animationPlayState = 'running';
}

By adding the above JavaScript code, the animation will be paused when the mouse hovers over the scroll container and restarted when the mouse leaves.

So far, we have completed all the steps to use CSS to achieve seamless scrolling text display effects. You can adjust the style and animation properties according to your own needs to get a scrolling effect that is more in line with your web design style.
