css - HTML 머티리얼 디자인 버튼

카드를 연결함으로써 링크를 클릭 할 때 카드가 팝업되기를 원한다고 생각합니다. 이것은 javascript/jquery를 사용하여 쉽게 달성 할 수 있습니다. 순수한 "해키"CSS 솔루션도 가능하지만 권장하지 않습니다.

다음 솔루션은 jQuery를 사용합니다

$(document).ready(function() {
  $(".dropdown-content a").click(function() {
    $(".background-mask").show();
    $(".demo-card-wide.mdl-card").show();
    $(".mdl-card__supporting-text").text(
      $(this).attr("data-content")
    );
    $(".demo-card-wide>.mdl-card__title").css('background', 'url(' + $(this).attr("data-img") + ') center / cover')
  });
  $(".mdl-button").click(function() {
    $(".demo-card-wide.mdl-card").hide();
    $(".background-mask").hide();
  });
});

/* Style The Dropdown Button */
