Force an image to fit and keep aspect ratio

Question

I want an image to fill the 100% of its container\'s width, and I want it to have a max-heigth property set to it, all this keeping the aspect ratio but allowing to lose any

Answer 1

You can try CSS3 object-fit, and see browser support tables.

CSS3 object-fit/object-position Method of specifying how an object (image or video) should fit inside its box. object-fit options include "contain" (fit according to aspect ratio), "fill" (stretches object to fill) and "cover" (overflows box but maintains ratio), where object-position allows the object to be repositioned like background-image does.

JSFIDDLE DEMO

.container {
  width: 200px; /*any size*/
  height: 200px; /*any size*/
}

.object-fit-cover {
  width: 100%;
  height: 100%;
  object-fit: cover; /*magic*/
}

<div class="container">
  <img class="object-fit-cover" src="https://i.stack.imgur.com/UJ3pb.jpg">
</div>

Answer 2

You can achieve this using css flex properties. Please see the code below

.img-container {
  width: 150px;
  height: 150px;
  border: 2px solid red;
  justify-content: center;
  display: flex;
  flex-direction: row;
  overflow: hidden;
  
}
.img-container .img-to-fit {
  flex: 1;
  height: 100%;
}

<div class="img-container">
  <img class="img-to-fit" src="https://images.pexels.com/photos/8633/nature-tree-green-pine.jpg" />
</div>
