Answer 1

In CSS, the background-size property can transform the way the background image proportions itself to the element.

background-size: cover

Edit:

If you want to keep the structure, you can use CSS object-fit properties https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit

Answer 2

You can use background-size: 100% 100% for this:

div {
  margin-bottom: 1em;
  width: 300px;
  height: 200px;
  border: 3px solid black;
  background: url(https://unsplash.it/100x100);
  background-repeat: no-repeat;
  background-size: 100% 100%;
}

div:nth-of-type(2) {
  width: 100px;
  height: 400px;
}

div:nth-of-type(3) {
  width: 500px;
  height: 200px;
}

<div></div>
<div></div>
<div></div>

Here's a re-sizeable example using background:

div{
  resize:both;
  overflow:hidden;
  width:200px;
  height:300px;
  background:url(https://picsum.photos/200/300)no-repeat 0 0;
  background-size:100% 100%;
}

<div></div>

Here's another using img:

div{
  resize:both;
  overflow:hidden;
  height:300px;
  width:200px;
}
img{
  width:100%;
  height:100%;
}

<div>
  <img src="https://picsum.photos/200/300"/>
</div>
