Maintain aspect ratio when page is resized or viewed on a different device

I’m working on a project and I want my webpage to maintain its style and aspect ratio anytime it is resized or viewed on any device. I have tried to use the position attribute (position:fixed;) on CSS but it’s not working. How can this be done using CSS?

    figure {
    width: 36%;
    margin: 8px auto;
}
 
div.relative_div {
    width: 100%;
    padding-bottom: 56.25%; /* 16:9 */
    position: relative;
    background: black;
}
 
div.relative_div > div {
    position: absolute;
    top: 0; bottom: 0; left: 0; right: 0;
    color: white;
    font-size: 24px;
    text-align: center;
}
<html>
<body>
<figure>
    <div class="relative_div">
        <div>Relative Aspect Ratio </div>
    </div>
</figure>
</body>
</html>

As you can see in the CSS, all we have to do is nest an element with 100% width inside a “responsive” percentage-based-width parent element, and then declare a % for bottom or top padding based on the ratio we want to maintain. To calculate the percentage needed for any aspect ratio we can use the following formula:

B / (A / 100) = C%

So for 16:9 (where 16 is A and 9 is B):

9 / .16 = 56.25 (%)
