Methods and techniques on how to achieve seamless scrolling news through pure CSS

With the continuous development of Web technology, how to achieve some cool effects through CSS has become The pursuit of front-end developers. This article will introduce methods and techniques on how to achieve seamless scrolling news through pure CSS, and provide specific code examples.

1. Implementation Ideas
There are generally two ideas for realizing the seamless scrolling news effect: using CSS animation and using the transform attribute of CSS3. Below we will introduce these two methods one by one.

1. Use CSS animation
CSS animation defines animation effects through key frames (@keyframes), and applies animation to elements through the animation attribute. The key to achieving seamless scrolling news is to achieve the effect of seamless scrolling through infinite loops of animation.

The specific implementation steps are as follows:
(1) Create a div container and set its width to the width of the scrolling content.
(2) Insert scrolling content in the container and set it as an inline element.
(3) Use CSS animation to achieve the scrolling effect, and control the scrolling speed and effect by setting the duration and timing-function properties of animation.
(4) Make the animation loop infinitely by setting the infinite attribute of animation.

The sample code is as follows:

<div class="news-container">
  <ul class="news">
    <li>新闻1</li>
    <li>新闻2</li>
    <li>新闻3</li>
    <li>新闻4</li>
    <li>新闻5</li>
    <!-- 添加更多新闻 -->
  </ul>
</div>

.news-container {
  width: 400px;
  overflow: hidden;
}

.news {
  list-style: none;
  padding: 0;
  margin: 0;
  white-space: nowrap;
  animation: scroll-news 10s linear infinite;
}

.news li {
  display: inline;
  margin-right: 20px;
}

@keyframes scroll-news {
  0% {
    transform: translateX(0);
  }
  100% {
    transform: translateX(-100%);
  }
}

In the above code, the news content is translated to the left through the keyframe animation scroll-news. translateX(-100%) means to translate the element to the left. One hundred percent of its own width, achieving the scrolling effect.

2. Use the Transform property of CSS3
The Transform property of CSS3 is a method that can rotate, scale, translate and bevel elements. When implementing seamless scrolling of news, we can use TranslateX in the Transform attribute to translate the element.

The specific implementation steps are as follows:
(1) Create a div container and set its width to the width of the scrolling content.
(2) Insert scrolling content in the container and set it as an inline block element.
(3) Realize the scrolling effect by setting the Transform attribute, and control the scrolling speed and effect by setting the ease-in-out attribute of the transition.

The sample code is as follows:

<div class="news-container">
  <ul class="news">
    <li>新闻1</li>
    <li>新闻2</li>
    <li>新闻3</li>
    <li>新闻4</li>
    <li>新闻5</li>
    <!-- 添加更多新闻 -->
  </ul>
</div>

.news-container {
  width: 400px;
  overflow: hidden;
}

.news {
  list-style: none;
  padding: 0;
  margin: 0;
  white-space: nowrap;
  animation: scroll-news 10s linear infinite;
}

.news li {
  display: inline-block;
  margin-right: 20px;
  transition: transform 1s ease-in-out;
}

.news li:hover {
  transform: translateX(-100%);
}

In the above code, by setting the :hover pseudo-class selector and Transform property, when the mouse is hovering over the news list, the element will be translated to the left by itself One hundred percent of the width to achieve the scrolling effect.

2. Precautions
In the process of achieving seamless scrolling news effect, there are some precautions that we need to pay attention to:

1. Make sure the width of the container is enough to accommodate the scrolling content.
2. Set the overflow attribute of the container to hidden to hide content beyond the scope of the container.
3. Set the scrolling content to be an inline or inline block element to achieve a horizontal arrangement effect.
4. Set the margins between news items to maintain spacing between scrolling content.
5. Achieve scrolling effect by using animation or Transform property, and set up infinite loop.

Through the above methods and techniques, we can easily achieve the effect of seamless scrolling news through pure CSS. I hope this article can be helpful to you. If you are interested in learning more about CSS, you can continue to explore the wonderful effects of other CSS.
