如何创建特定的模态框

Question

我试图创建模态框动画时遇到了这个小问题。我已经设法使背景变黑，模态框滑入，但是当我点击关闭按钮时，只有模式框会滑动，而不是背景恢复正常，让我点击页面上的其他任何东西 请帮助，提前致谢。

.modal{ 
display:none; 
z-index:99; 
position:fixed; 
left:0; 
top:0; 
height:100%; 
width:100%; 
background-color: rgba(0,0,0,0.7); 
animation-duration: 0.4s; 
animation-fill-mode: forwards; 
} 

.modal-content{ 
position:relative; 
width:90%; 
height:90%; 
margin: 2% auto; 
background-color: #dfdde0; 
display:none; 
animation-fill-mode: forwards; 
animation-name:slide-down-modal; 
animation-duration: 0.6s; 
} 

.modal-content img{ 
float:right; 
height:24px; 
width:24px; 
margin-top:10px; 
margin-right:10px; 
opacity:0.5; 
} 

.modal-content img:hover{ 
opacity:1; 
} 

@keyframes slide-down-modal{ 
from{top:-700px} 
to{top:0} 
} 

@keyframes slide-up-modal{ 
from{top:0; opacity:1} 
to{top:-700px; opacity:0} 
} 

这里是JavaScript部分

function openModal(){ 
var modal=document.getElementsByClassName("modal")[0]; 
var modalContent=document.getElementsByClassName("modal-content")[0]; 
modal.style.display="block"; 
modalContent.style.display="block"; 
} 

function closeModal(){ 
var modal=document.getElementsByClassName("modal")[0]; 
var modalContent=document.getElementsByClassName("modal-content")[0]; 
modalContent.style.animationName="slide-up-modal"; 
if($(".modal").css("display")=="block"){ 
    $(".modal").css("display", "none"); 
}; 
} 

和HTML

<div onclick="openModal()">click me</div> 
    <div class="modal"> 
     <div class="modal-content"> 
      <img onclick="closeModal()" src="X.png"> 
     </div> 
    </div> 

不知何故，我设法关闭这两个，但同时，虽然:(

$(".openModal").click(function(){ 
 
\t $(".modal").fadeIn("slow", function(){ 
 
    \t $(this).find(".modal-content").fadeIn("slow"); 
 
    }); 
 
}); 
 
$(".closeModal").click(function(){ 
 
\t $(".modal-content").fadeOut("slow", function(){ 
 
    \t $(this).parent(".modal").fadeOut("slow"); 
 
    }); 
 
});

.modal{ 
 
display:none; 
 
z-index:99; 
 
position:fixed; 
 
left:0; 
 
top:0; 
 
height:100%; 
 
width:100%; 
 
background-color: rgba(0,0,0,0.7); 
 
animation-duration: 0.4s; 
 
animation-fill-mode: forwards; 
 
} 
 

 
.modal-content{ 
 
position:relative; 
 
width:90%; 
 
height:90%; 
 
margin: 2% auto; 
 
display:none; 
 
background-color: #dfdde0; 
 
animation-fill-mode: forwards; 
 
animation-name:slide-down-modal;
