  <source srcset="cat-image-720.avif 720w" type="image/avif" />
  <source srcset="cat-image-1080.avif 1080w" type="image/avif" />

  <source srcset="cat-image-480.jpg 480w" type="image/jpg" />
  <source srcset="cat-image-720.jpg 720w" type="image/jpg" />
  <source srcset="cat-image-1080.jpg 1080w" type="image/jpg" />
