How to use HTML, CSS and jQuery to implement seamless scrolling news notifications

In today's era of information explosion, news notifications have become one of the important ways for people to obtain instant information. one. News notification bars on web pages can attract users' attention and provide important and interesting content. This article will introduce how to use HTML, CSS and jQuery to implement a seamless scrolling news notification bar, with specific code examples.

1. HTML structure:

In the HTML file, we first need to create a container containing news notifications.

<div class="news-container">
  <ul class="news-list">
    <li><a href="#">这是第一条新闻通知</a></li>
    <li><a href="#">这是第二条新闻通知</a></li>
    <li><a href="#">这是第三条新闻通知</a></li>
    <!-- 其他新闻通知... -->
  </ul>
</div>

In the above code, we use a div element as the news notification container, and nest a ul list in div. Each news notification is wrapped with the li tag, and a link <a></a> can be added.

2. CSS styles:

In order to achieve the seamless scrolling effect, we need to set some basic CSS styles for the news notification container and news list.

.news-container {
  overflow: hidden;
}
.news-list {
  list-style: none;
  padding: 0;
  margin: 0;
  white-space: nowrap;
}

.news-list li {
  display: inline-block;
  margin-right: 20px;
  padding: 10px;
  background-color: #f4f4f4;
  border-radius: 5px;
}

In the above code, we set the overflow property of the news notification container to hidden to hide the content overflow part.

3. jQuery scrolling effect:

Using the jQuery library can simplify the code we use to achieve the scrolling effect. Below is a code example for seamless scrolling using jQuery.

$(function() {
  function scrollNews() {
    $('.news-list li:first').slideUp(function() {
      $(this).appendTo($('.news-list')).slideDown();
    });
  }
  
  setInterval(scrollNews, 3000); // 每隔3秒滚动一次
});

In the above code, we first define a scrollNews function, in which the scrolling effect is achieved by using the slideUp and slideDown functions. slideUpSlide the first news notification up, then add it to the end of the list with the appendTo function, and use slideDown to display the new news notification.

Finally, use the setInterval function to call the scrollNews function regularly to achieve the automatic scrolling effect. In the example above, the setting scrolls every 3 seconds, but you can adjust this to suit your needs.

4. Complete sample code:

The following is a complete example of the above-mentioned code. You can directly copy and paste it into an HTML file and see the effect.

<script>
$(function() {
  function scrollNews() {
    $('.news-list li:first').slideUp(function() {
      $(this).appendTo($('.news-list')).slideDown();
    });
  }
  
  setInterval(scrollNews, 3000); // 每隔3秒滚动一次
});
</script>


<div class="news-container">
  <ul class="news-list">
    <li><a href="#">这是第一条新闻通知</a></li>
    <li><a href="#">这是第二条新闻通知</a></li>
    <li><a href="#">这是第三条新闻通知</a></li>
    <!-- 其他新闻通知... -->
  </ul>
</div>

At this point, we have implemented a seamless scrolling news notification bar by using HTML, CSS and jQuery. You can adjust the style and code according to actual needs to meet your website needs. Hope this article is helpful to you!
