</script>

<msc-collages>
  <script type="application/json">
    {
      "theme": 8, // 1 ~ 8
      "object-fit": "cover", // cover || contain
      "collages": [
        {
          "link": "?",
          "src": "https://picsum.photos/300/300?grayscale&random=1",
          "alt": "grayscale 1",
          "target": "_blank"
        },
        {
          "link": "?",
          "src": "https://picsum.photos/300/300?grayscale&random=2",
          "alt": "grayscale 2",
          "target": "_blank"
        },
        {
          "link": "?",
          "src": "https://picsum.photos/300/300?grayscale&random=3",
          "alt": "grayscale 3",
          "target": "_blank"
        },
        {
          "link": "?",
          "src": "https://picsum.photos/300/300?grayscale&random=4",
          "alt": "grayscale 4",
          "target": "_blank"
        }
      ]
    }
  </script>

document.body.appendChild(nodeA);
nodeA.theme = 1;
nodeA.collages = [ {...} ];

// new instance with Class
const nodeB = new MscCollages();
document.body.appendChild(nodeB);
nodeB.theme = 2;
nodeB.collages = [ {...}, {...} ];

// new instance with Class & default config
const config = {
  theme: 3,
  collages: [
    {...},
    {...},
    ...
