How to realize the flexible layout of the grid system through CSS Flex elastic layout

With the popularity of mobile devices and the diversification of web browsing, responsive web design has become The key to modern web design. In order to achieve flexible layout on different devices, grid systems are increasingly favored by developers.

In the past, grid systems were primarily implemented using floating and fixed-width grids. However, this traditional approach can become cumbersome and inflexible when dealing with complex web page layouts. CSS Flex elastic layout provides us with a simpler and more powerful way to implement flexible layout of the grid system.

This article will introduce how to use CSS Flex elastic layout to achieve flexible layout of the grid system, and provide specific code examples.

Basic structure of layout
Before we begin, we need to determine the basic structure of the grid system. Generally speaking, a grid system consists of rows and columns. Each row contains multiple columns, each column taking up a portion of the page width.

Using CSS Flex elastic layout, we can divide the layout of the grid system into two parts: containers and items. Containers are rows and items are columns.

Container
First, we need to create a container to serve as the rows of the grid system. The container's style should be set to display: flex, and the associated flex properties set to determine how the rows are laid out.

.container {
  display: flex;
  flex-wrap: wrap;
}

This code will create a flexible container that wraps based on the size of the items inside and automatically resizes when needed.

Items
Inside the container, we need to add items as columns for the grid system. Items should be styled to flex-grow: 1 to ensure that all columns automatically expand or contract as needed.

.item {
  flex-grow: 1;
}

This code will create a flexible item that automatically resizes itself based on the size of other items within the container.

Sample code of grid system
The following is a sample code that uses CSS Flex elastic layout to implement a grid system:

<div class="container">
  <div class="item">Col 1</div>
  <div class="item">Col 2</div>
  <div class="item">Col 3</div>
</div>

.container {
  display: flex;
  flex-wrap: wrap;
}

.item {
  flex-grow: 1;
}

In this example, we create a grid system with three columns grid system. The width of each column will automatically adjust based on the width of the container and the width of the other columns.

In addition to the basic grid system layout, we can also use other properties and techniques of CSS Flex to achieve more complex and flexible layouts.

Summary
By using CSS Flex layout, we can easily create a flexible layout of the grid system. By styling containers and items, we can implement a grid system with automatic word wrapping and automatic sizing.

In actual development, we can also combine media queries and other CSS properties to create a responsive grid system to adapt to the screen sizes and resolutions of different devices.
