How to Fix Image Overflow and Distortion with CSS Object-Fit?

CSS Object-Fit: Maintain Image Aspect Ratio in Responsive Layouts

When utilizing CSS's object-fit: contain property to ensure images remain responsive within flexbox containers, you may encounter an issue where the layout retains the original image width, resulting in unnecessary scrollbars.

Understanding Object-Fit

Before delving into the issue at hand, let's clarify how object-fit operates. The property defines how the content of an element should be scaled and positioned within its bounding box. When set to contain, the content (in our case, the image) will resize proportionately, maintaining its aspect ratio, and fit within the available space.

The Original Image Width Issue

In the provided code snippet, you've defined containers with overflow: auto, which introduces a scrollbar when the content exceeds the container's width. However, the image's width remains at its original size, causing the layout to accommodate the image's initial dimensions.

Solution

To rectify this, you need to explicitly set the width of the images using CSS's width property. This will ensure that the image's width conforms to the container's width, allowing the object-fit property to correctly scale and position the image while preserving its aspect ratio.

Updated Code

Here's an updated version of your CSS code that includes the width property:

<code class="css">img {
  object-fit: contain;
  width: 100%;
}</code>

By adding the width: 100% rule, you're instructing the browser to fit the image's width precisely to its container, allowing the object-fit: contain property to function as intended.
