Chamar um arquivo HTML dentro de um modal Lightbox

MNunes473 · Novembro 9, 2017

Boa tarde a todos,

O caso é o seguinte:

Uso o Modal Lightbox para uma galeria de imagens, no index tenho os thumbs e ao clicar abre o modal com a imagem maximizada.

Devido a quantidade de imagens demora muito para carregar todas.

Como posso chamar um arquivo html contendo as imagens para dentro do modal da index? Assim não carregaria essas imagens ao carregar a index.

 body {
      font-family: Verdana, sans-serif;
      margin: 0;
    }

    * {
      box-sizing: border-box;
    }

    .row > .column {
      padding: 0 8px;
    }

    .row:after {
      content: "";
      display: table;
      clear: both;
    }

    .column {
      float: left;
      width: 25%;
    }

    /* The Modal (background) */
    .modal {
      display: none;
      position: fixed;
      z-index: 1;
      padding-top: 100px;
      left: 0;
      top: 0;
      width: 100%;
      height: 100%;
      overflow: auto;
      background-color: black;
    }

    /* Modal Content */
    .modal-content {
      position: relative;
      background-color: #fefefe;
      margin: auto;
      padding: 0;
      width: 90%;
      max-width: 1200px;
    }

    /* The Close Button */
    .close {
      color: white;
      position: absolute;
      top: 10px;
      right: 25px;
      font-size: 35px;
      font-weight: bold;
    }

    .close:hover,
    .close:focus {
      color: #999;
      text-decoration: none;
      cursor: pointer;
    }

    .mySlides {
      display: none;
    }

    .cursor {
      cursor: pointer
    }

    /* Next & previous buttons */
    .prev,
    .next {
      cursor: pointer;
      position: absolute;
      top: 50%;
      width: auto;
      padding: 16px;
      margin-top: -50px;
      color: white;
      font-weight: bold;
      font-size: 20px;
      transition: 0.6s ease;
      border-radius: 0 3px 3px 0;
      user-select: none;
      -webkit-user-select: none;
    }

    /* Position the "next button" to the right */
    .next {
      right: 0;
      border-radius: 3px 0 0 3px;
    }

    /* On hover, add a black background color with a little bit see-through */
    .prev:hover,
    .next:hover {
      background-color: rgba(0, 0, 0, 0.8);
    }

    /* Number text (1/3 etc) */
    .numbertext {
      color: #f2f2f2;
      font-size: 12px;
      padding: 8px 12px;
      position: absolute;
      top: 0;
    }

    img {
      margin-bottom: -4px;
    }

    .caption-container {
      text-align: center;
      background-color: black;
      padding: 2px 16px;
      color: white;
    }

    .demo {
      opacity: 0.6;
    }

    .active,
    .demo:hover {
      opacity: 1;
    }

    img.hover-shadow {
      transition: 0.3s
    }

    .hover-shadow:hover {
      box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2), 0 6px 20px 0 rgba(0, 0, 0, 0.19)
    }
