CSS Properties aspect-ratio vs object-fit-CodePudding

I am a little new to CSS. I am trying to apply to an image a 16:9 ratio.

I have seen both the object-fit and aspect-ration properties.

Do I need the object-fit property if I just use the aspect-ratio: 16/9 property ?

I did read an article New aspect-ratio CSS property and the writer uses both.

Can someone please clarify this?

CodePudding user response：

Here's an example of why you would want to combine aspect-ratio with object-fit: So your image doesn't get stretched.

You can control the composition within the newly specified aspect ratio using object-fit and object-position.

img {
  border: 2px solid red;
  width: 190px;
}

label {
  display: inline-block;
}

span {
  display: block;
  font-size: 13px;
  text-align: center;
}

.ar {
  aspect-ratio: 16/9;
}

.of {
  object-fit: cover;
}
