How to Prevent Scrollbars with object-fit: Contain in Flexbox Containers?

CSS Object-Fit: Contain Preserves Image Dimensions in Layout

Problem:

When using object-fit: contain to resize images within flexbox containers, the images adjust responsively, but the original image width remains, resulting in scrollbars appearing.

Exploration:

object-fit defines how an image should behave when its container has different dimensions than the image itself. object-fit: contain ensures that the image fits within the container without cropping, keeping its aspect ratio intact.

Missing CSS Attributes:

To resolve the issue, additional CSS attributes are required to specify the width and height of the container.

Solution:

Instead of relying on the image's original width, set the container's width explicitly using width. Additionally, specify the container's height to match the aspect ratio of the image using height.

Updated CSS Code:

<code class="css">.half-containers {
  flex: 0 1 50%;
  width: 50%;  /* Specify explicit width for the container */
  height: calc(50% / aspect-ratio);  /* Calculate height based on aspect ratio */
  overflow: auto;
  box-sizing: border-box;
  border: 0.5px solid red;
  display: flex;
}</code>

Concept Explanation:

By defining the container's width and height explicitly, we ensure that the image can scale within the defined dimensions while maintaining its aspect ratio. The calculated height ensures that the image fits within the container without distorting it, even when its original width exceeds the container's width.
