With the development of web design, people have higher and higher requirements for web page layout. In order to achieve even distribution of web content, CSS3's flexbox technology has become a very effective solution.

1. What is flexbox technology
Flexbox (flexible layout) is a newly added layout mode in CSS3. It provides a flexible way to arrange, align and allocate space for elements. Using flexbox technology, we can easily achieve even distribution of web page content without resorting to complex styles and additional code.

}
In this example, if there are 3 child elements in the container, they will Distribute the width of the parent container evenly.
.container {

}
In this example, the child elements will be in the parent container Distributed horizontally, aligned with the start and end of the parent container, the space within it will be evenly distributed.
.container {
