Sample code for easily implementing page layout using flex layout

Without further ado, let's get straight to the code:

1. Top, middle and bottom layout:

<!DOCTYPE html>

    <html lang="en">
    <head>
     <meta charset="UTF-8">
     <meta name="viewport" content="width=device-width, initial-scale=1.0">
     <title>Document</title>
     <style>
     body {
     position: absolute;
     left: 0; right: 0; top: 0; bottom: 0;
     padding: 0; margin: 0;
     display: flex;
     flex-direction: column;
     }
     .header, .footer {
     height: 50px;
     }
     .body {
     flex-grow: 1;
     background-color: #DDD;
     }
     </style>
    </head>
    <body>
     <div class="header">Header</div>
     <div class="body">Content</div>
     <div class="footer">Footer</div>
    </body>
    </html>

The display effect is as follows:

2. Left and right layout:

    <!DOCTYPE html>
    <html lang="en">
    <head>
     <meta charset="UTF-8">
     <meta name="viewport" content="width=device-width, initial-scale=1.0">
     <title>Document</title>
     <style>
     body {
     position: absolute;
     left: 0; right: 0; top: 0; bottom: 0;
     padding: 0; margin: 0;
     display: flex;
     }
     .left, .right {
     height: 100%;
     }
     .left {
     width: 250px;
     background-color: rgba(255,0,0,0.3);
     }
     .right {
     display: flex;
     flex-direction: column;
     }
     .header, .footer {
     height: 50px;
     }
     .right, .content {
     flex-grow: 1;
     }
     .content {
     background-color: #DDD;
     }
     </style>
    </head>
    <body>
     <div class="left">LeftNav</div>
     <div class="right">
     <div class="header">Header</div>
     <div class="content">Content</div>
     <div class="footer">Footer</div>
     </div>
    </body>
    </html>

The page effect is as follows:

Here are a few key styles that will allow you to design any layout you want:

flex-grow: 1; // Indicates that when the width of the main axis of the container is redundant, the child item occupies the remaining space position: absolute; left: 0; right: 0; top: 0; bottom: 0; // This set of styles allows the element to fully occupy the positioned parent element
