jQuery is a powerful JavaScript library widely used in website development. It provides hundreds of special effects and plug-ins for web development, including plug-ins for DIV floating. In this article, we will introduce how to implement DIV floating using jQuery.

Use CSS to implement DIV floating

Before introducing how to use jQuery to implement DIV floating, let’s first take a look at how to use CSS to implement DIV floating. There is a float property in CSS that floats an element to the left or right and allows other elements to wrap around it. The following is an example:

<div style="float:left">左浮动</div>
<div style="float:right">右浮动</div>
<div style="clear:both"></div>

The above code demonstrates how to float two DIV elements to the left and right respectively, and insert an empty DIV behind them to clear the floating effect. This can avoid the problem of height collapse of the parent element.

Use jQuery to implement DIV floating

In the above example, we used the float attribute to implement DIV floating. But if we want to achieve DIV floating under dynamic loading, we can't do it just using CSS. At this time, you need to use jQuery to realize DIV floating.

The following is a sample code:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8" />
    <title>jQuery实现DIV浮动</title>
    <script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script>
    <style>
      .float-box {
        width: 200px;
        height: 100px;
        margin: 20px 20px 20px 0;
        background-color: #ccc;
        float: left;
      }
    </style>
  </head>
  <body>
    <div id="container"></div>
    <script>
      $(function() {
        for (var i = 0; i < 10; i++) {
          var div = $("<div class='float-box'><p>浮动元素 " + i + "</p></div>");
          $("#container").append(div);
        }
        var clear = $("<div style='clear:both'></div>");
        $("#container").append(clear);
      });
    </script>
  </body>
</html>

In this code, we first insert a DIV named "container" into the HTML page to store the elements we want to float. Then use jQuery in JavaScript to dynamically create 10 DIV elements named "float-box" and insert an empty DIV at the end to clear the float.

It should be noted that we have clearly defined the floating method of each DIV element as left floating in CSS. In this way, the floating elements will automatically wrap, forming a left-aligned effect.

Summary

Through the above examples, we can see that it is very simple to use jQuery to implement DIV floating. We just need to use jQuery in JavaScript to dynamically create the elements to be floated, and then explicitly specify how they float in CSS. At the same time, inserting an empty DIV after the floating element can avoid the problem of height collapse.

jQuery can also realize DIV floating through other plug-ins, including Masonry, Isotope, Packery, etc. These plug-ins are more flexible and diverse than simple floating methods and can make web page layouts more attractive.
