Ivan, according to the website Can I Use the template tag is not supported by IE, Opera Mini and the Android 4.3.

but for these cases, you can use a Polyfill, as implemented by jeffcarp.:

(function () {
  if ('content' in document.createElement('template')) {
    return false;
  }

  var templates = document.getElementsByTagName('template');
  var plateLen = templates.length;

  for (var x = 0; x < plateLen; ++x) {
    var template = templates[x];
    var content = template.childNodes;
    var fragment = document.createDocumentFragment();

    while (content[0]) {
      fragment.appendChild(content[0]);
    }

    template.content = fragment;
  }
})();
