How to create a dynamic tag cloud using HTML, CSS and jQuery

The tag cloud is a common web design element that is often used to display the tags or tags of a website. Keywords so that users can quickly browse and select content of interest. This article will introduce how to use HTML, CSS and jQuery to create a dynamic tag cloud, and provide specific code examples.

HTML structure
First, we need to create a basic HTML structure to hold the tag cloud. Typically, a tag cloud is implemented as a container containing multiple linked elements with tags. Here is a sample HTML code:

<div class="tag-cloud">
   <a href="#" class="tag">HTML</a>
   <a href="#" class="tag">CSS</a>
   <a href="#" class="tag">JavaScript</a>
   <a href="#" class="tag">jQuery</a>
   <a href="#" class="tag">Web设计</a>
   <a href="#" class="tag">前端开发</a>
   <!-- 添加更多标签 -->
</div>

CSS Styles
Next, we need to add CSS styles for the tags and tag cloud containers. The following is a CSS code example:

.tag-cloud {
   text-align: center;
   padding: 10px;
}

.tag {
   display: inline-block;
   padding: 5px 10px;
   margin: 5px;
   background-color: #eee;
   color: #333;
   border-radius: 5px;
   text-decoration: none;
   transition: background-color 0.3s ease;
}

.tag:hover {
   background-color: #ddd;
}

Here we set the center alignment and padding for the tag cloud container. Each label uses the display attribute of the inline block element and adds some styles, such as padding, margins, background color, color, rounded border, etc.

jQuery dynamic effects
Finally, we need to use jQuery to add some dynamic effects to the tag cloud to enhance the user experience. The following is a jQuery code example:

$(document).ready(function() {
   $('.tag').click(function(e) {
      e.preventDefault();
      $(this).toggleClass('active');
   });
});

Here we use jQuery's .ready() method to ensure that the code is executed after the document is loaded. We added a click event handler for each label, switching the active class on click. This way, when the user clicks on a tab, its style changes to highlight the selected tab.

Full code example
The following is the complete HTML file of the entire code example:

<!DOCTYPE html>
<html>
<head>
   <title>动态标签云</title>
   <style>
      .tag-cloud {
         text-align: center;
         padding: 10px;
      }

      .tag {
         display: inline-block;
         padding: 5px 10px;
         margin: 5px;
         background-color: #eee;
         color: #333;
         border-radius: 5px;
         text-decoration: none;
         transition: background-color 0.3s ease;
      }

      .tag:hover {
         background-color: #ddd;
      }
   </style>
   <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
   <script>
      $(document).ready(function() {
         $('.tag').click(function(e) {
            e.preventDefault();
            $(this).toggleClass('active');
         });
      });
   </script>
</head>
<body>
   <div class="tag-cloud">
      <a href="#" class="tag">HTML</a>
      <a href="#" class="tag">CSS</a>
      <a href="#" class="tag">JavaScript</a>
      <a href="#" class="tag">jQuery</a>
      <a href="#" class="tag">Web设计</a>
      <a href="#" class="tag">前端开发</a>
      <!-- 添加更多标签 -->
   </div>
</body>
</html>
