I believe you have discovered some changes from the comparison between Figure 1 and Figure 2. When the CSS floating attribute is not set in Figure 1, the two img images are displayed from left to right in the same row, and there is a gap between the two images. In Figure 2, after we added the floating attribute float right, the two img elements began to float and display from right to left without any gaps. If we need a gap at this time, we must use the padding attribute. So we can know that the css floating attribute float can control the element to float to the right by setting the right value.

2. CSS floating attribute-float left attribute code example

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>css float left属性使用示例</title>
    <style>
        .demo{
            width: 100px;height: 100px;
            background-color: #ccccff;
        }
        .demo1{
            float: left;
            width: 100px;height: 100px;
            background-color: #b2ecef;
        }
     </style>

By comparing Figure 3 and Figure 4, we can clearly find that the demo1 element floats to the left. Similarly, if we want a gap between two elements, we can achieve it through the padding attribute.

To sum up, the css float attribute can control any element to float left or right. The css float property can be used not only to control the floating of images, but also to control the floating of text.
