Two DIV backgrounds with different sizes

Question

Essentially, the title says it all all.

div {
  border-radius: 4px;
  background-image: url(IMAGE1.PNG), url(IMAGE2.PNG);
  box-shadow: 0 0 10px rgba(0,0,0,0.75), inset 1px 1px 2px #fff, inset -1px -1px 1px #777;
}

Essentially, I want image1 to maintain default properties as the typical background, but I want image2 to be set to something equivalent to background-size: cover;

Answer 1

background-size accepts multiple values too.

background-size: auto, cover;

var pattern = Trianglify({
  height: 300,
  width: 300,
  cell_size: 40,
});

var div = document.getElementsByTagName('div')[0];

div.style.backgroundImage = "url('https://i.sstatic.net/955qe.png'), url('" + pattern.png() + "')";

div {
  border-radius: 4px;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.75), inset 1px 1px 2px white, inset -1px -1px 1px #777;
  background-position: center;
  background-repeat: no-repeat;
  background-size: auto, cover;
  height: 140px;
  width: 300px;
}
