In order to maintain the aspect ratio of a div with CSS create flexible elements that keep their aspect ratio (4:3, 16:9, etc.) when resize the browser window.

What is aspect ratio? 

The aspect ratio of an element describes the proportional relationship between its width and height. Two common video aspect ratios are 4:3 and 16:9.
To maintain the aspect ratio of the div add a percentage value for padding-top. Different aspect ratio have different percentage values. Some of them are shown below: 

aspect ratio  | padding-top value
1:1 | 100%
16:9 | 56.25%
4:3 | 75%
3:2 | 66.66%
8:5 | 62.5%


element {
padding-top: %value;



<!DOCTYPE html>
    <meta name="viewport"
        .container {
            background-color: green;
            position: relative;
            width: 100%;
            padding-top: 56.25%; /* 16:9 Aspect Ratio */
        .text {
            position: absolute;
            top: 0;
            left: 0;
            bottom: 0;
            right: 0;
            text-align: center;
            font-size: 25px;
            color: white;
        .example {
            background: white;
            color: green;
            font-size: 40px;
            padding-bottom: 20px;
    <div class="container">
        <div class="text">
            <div class="example">
