object-fit: cover and IE11

I'm using object-fit: cover; in my CSS to line up images on a page, because they need to be the same height. It works perfectly in most browsers however IE11 is distorting the images.

I read that I might be able to use @support to fix this but I don't understand how to do this? Or is there another option that I might be able to use?

The code I have used is below - would really appreciate any help.

.brands {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(150px, 1fr));
  grid-gap: 1rem;
}

.brands__item img {
  display: block;
  /* Make sure max-width is added */
  max-width: 100%;
  height: 70px;
}
    
.brands__item img {
  width: 130px;
  height: 75px;
  object-fit: contain;
}   
    
.brands__item a {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100%;
}
    


<div class="row" style="padding: 10px 30px 40px;">
    <hr style="border-color: #000000; border-width: 2px; width: 90px; margin-bottom: 10px;" />
<h5 style="text-align: center;font-size: 2.4rem;margin-bottom:30px;">Trending now</h5>
<ul class="brands">
  <li class="brands__item">

Solution

I test your code in IE 11 and the issue seems not only with object-fit.

CSS Grid part of your code doesn't work in IE 11.
- You need to use -ms- prefix to elements such as display: grid, grid-column and grid-row.
- grid-template-areas isn't supported, you can convert it to work with grid lines.
- The repeat() notation doesn't work in IE 11. You need to write in all row and column lengths.
object-fit is not supported by IE 11. You can refer to this thread for the fix.

I use @media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {} to target IE 11 in CSS to add some codes for IE 11 to fix the issue. The added code is like below:

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    .brands__item img {
        width: 130px;
        height: auto;
        max-width: 100%;
        max-height: 100%;
    }

    .brands {
        display: -ms-grid;
        -ms-grid-columns: 1fr 1fr 1fr 1fr 1fr 1fr;
    }

    li:nth-of-type(1) {
        -ms-grid-column: 1;
        -ms-grid-row: 1;
    }

    li:nth-of-type(2) {
        -ms-grid-column: 2;
        -ms-grid-row: 1;
    }

    li:nth-of-type(3) {
        -ms-grid-column: 3;
        -ms-grid-row: 1;
    }

    li:nth-of-type(4) {
        -ms-grid-column: 4;
        -ms-grid-row: 1;
    }

    li:nth-of-type(5) {
        -ms-grid-column: 5;
        -ms-grid-row: 1;
    }

    li:nth-of-type(6) {
        -ms-grid-column: 6;
        -ms-grid-row: 1;
    }
}
