How can I make all images of different height and width the same via CSS?

Applying uniform size concepts

Making your div containers uniform

For fabulous grid arrangements, it's helpful to use div containers:

.div-same-size {
  width: 150px;
  height: 200px;
  overflow: hidden; /* Images can't play hide and seek anymore */
}

.div-same-size img {
  width: 100%;
  height: 100%;
  object-fit: cover;
}


<div class="div-same-size">
  <img src="image.jpg" />
</div>


Using this approach not only prevents overflow but also keeps your layout looking sharp.

Applying the scale-down method for larger images

When your Brady Bunch sized pics need to go on a diet without getting cropped:

.img-scale-down {
  max-width: 100%;  /* Scale down if content is bloated */
  height: auto;     /* Maintain the original shape */
  object-fit: scale-down; /*Just making sure no stretching happens */
}


Images will stay in tip-top shape without causing any discomfort to their smaller companions.

Applying responsive sizing for images

If your target is a responsive site, use relative units:

.img-responsive {
  width: 20vw;   /* Responsive width */
  height: 30vw;  /* Height varies based on viewport width "vw" */
  object-fit: cover; /* No aspect ratio left behind */
}


Take care to select your relative units wisely to maintain the aspect ratio.

Extending your understanding of uniformity

Centring images within containers

For smaller images than the reserved space:

.img-center {
  position: relative;
  overflow: hidden; /* Preventing the image from taking a walk */
}

.img-center img {
  position: absolute;
  top: 50%; /* place it in the middle... */
  left: 50%; /* ... and don't let it run away */
  transform: translate(-50%, -50%); /* "Stay just where you are!" */
}


This procedure ensures the images are always at the centre, like a trophy in a display case.

Thinking about content relevance

'object-fit: cover' might clip vital parts of an image. To avoid cropping the heart of your image:

• Consider how the image tells its story
• Make sure significant details won't get sliced off
• object-fit: contain could be your best bet if all of an image is important

Backups for object-fit

Not all browsers are hip, so some don't support object-fit. Maintain a backup strategy:

.img-legacy {
  width: 150px;   /* Width that fits all */
  height: auto;   /* Height, you're free to choose your own size */
}


Include feature queries to apply object-fit only to those who can handle it:

@supports (object-fit: cover) {
  .img-legacy {
    object-fit: cover; /* "If you've got it, flaunt it!" */
  }
}

