The flexible box is composed of a flexible container (Flex container) and a flexible sub-element (Flex item).
A flexible container is defined as a flexible container by setting the value of the display property to flex or inline-flex. A flex container contains one or more flex child elements.
Note: The outside of the flexible container and inside the flexible sub-element are rendered normally. The flex box only defines how the flex child elements are laid out within the flex container.
Flexible sub-elements are usually displayed in one line within the flexible box. By default there is only one row per container.
Example:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>Document</title> </head> <!DOCTYPE html> <html> <head> <style> .flex-container { display: -webkit-flex; display: flex; width: 400px; height: 250px; background-color: lightgrey; } .flex-item { background-color: cornflowerblue; width: 100px; height: 100px; margin: 10px; text-align: center; line-height: 100px; } </style> </head> <body> <div class="flex-container"> <div class="flex-item">弹性容器 1</div> <div class="flex-item">弹性容器 2</div> <div class="flex-item">弹性容器 3</div> </div> </body> </html> </html>
