How Can I Preserve Image Aspect Ratio in CSS Flexbox While Allowing Flexible Height?

Preserving Image Aspect Ratio with Flexible Height

In the CSS flex box model, images often stretch or shrink to fill the width of their container. Maintaining the aspect ratio when adjusting the height can be a challenge. To address this issue, let's explore effective solutions.

One solution is utilizing object-fit on the image element:

object-fit: contain;

This property instructs the browser to contain the image within the designated space while preserving its proportions. You can view a live example at http://jsfiddle.net/ykw3sfjd/.

Alternatively, specific flex properties can be used:

align-self: center;
flex: 0 0 auto;

align-self ensures the image is vertically centered within the parent element, while flex: 0 0 auto controls the image's growth behavior. It prevents the image from stretching to fill the available height, allowing it to retain its aspect ratio.
