Why Isn't My `object-fit` Working in Flexbox?

Object-Fit Not Working in Flexbox: The Reason and Solution

Object-fit is a CSS property that controls how an image is resized to fit its container. However, in a flexbox layout, it may seem that object-fit is not working as expected.

The reason is that object-fit operates on the replaced element itself, not its container. In this case, the images are the replaced elements, not the wrapper div.

To make object-fit work as intended in flexbox, the images should become the flex items. By doing so, you set the flex properties on the images themselves, ensuring that object-fit is applied correctly.

Here's the modified code:

.container {
  display: flex;
  flex-direction: row;
  width: 100%;
}

img {
  object-fit: cover;
  flex: 1;
  margin-right: 1rem;
  overflow: hidden;
  height: 400px;
}

In this updated code, the images are the flex items, and object-fit is applied to them directly. Now, the images will resize to cover their entire containers while maintaining their aspect ratios.
