Maintaining Div's Aspect Ratio in CSS for Responsive Display

In the realm of responsive web design, maintaining an element's aspect ratio is crucial to ensure its visual integrity across different screen sizes. To achieve this, CSS offers a clever solution that automatically adjusts a div's height to match its width, preserving its square shape.

To implement this effect, simply apply the following CSS code to your div element:

div {
  height: 0;
  padding-bottom: 100%;
}

This technique utilizes a percentage-based padding on the div, effectively creating a square aspect ratio that scales proportionately with the div's width. The outer div acts as a placeholder for the square, while the inner div contains the actual content.

Additional Tips:

• Use the background-color property to add a background color to the div and enhance its visibility.
• Adjust the percentage value in the padding-bottom property to alter the aspect ratio as desired.

Code Example:

<div>

This technique is supported by most browsers and will ensure your div element maintains its square shape regardless of the parent's width.
