圖像與懸停效果，當你點擊YouTube視頻應該彈出一個燈箱

我試圖編碼圖像，轉向不同的圖像，通過懸停在它上面。通過點擊圖像，一個嵌入式視頻彈出（在燈箱中）。圖像與懸停效果，當你點擊YouTube視頻應該彈出一個燈箱

我試過幾種不同的東西。這是我現在的代碼。希望有人可以幫助我編寫一個嵌入式YouTube視頻彈出的燈箱，並將其懸停在它上面。順便說一句，我的目標是這樣的頁面 - >https://www.garyvaynerchuk.com/

非常感謝您的回答。不幸的是，這兩個提示並沒有真正解決。可能是因爲我用wordpress做這個項目，它不能很好地與JavaScript或jQuery相處。我現在通過使用插件「easy fancy box」解決了這個問題，並將以下代碼添加到我以前的代碼中。 – Yannick

HTML CSS &是不夠的，使用情態動詞，你需要了Javascript，以處理所有相關事件。

// Get the modal 
 
var modal = document.getElementById('myModal'); 
 

 
// Get the button that opens the modal 
 
var btn = document.getElementById("myBtn"); 
 

 
// Get the <span> element that closes the modal 
 
var span = document.getElementsByClassName("close")[0]; 
 

 
// When the user clicks on the button, open the modal 
 
btn.onclick = function() { 
 
    modal.style.display = "block"; 
 
} 
 

 
// When the user clicks on <span> (x), close the modal 
 
span.onclick = function() { 
 
    modal.style.display = "none"; 
 
} 
 

 
// When the user clicks anywhere outside of the modal, close it 
 
window.onclick = function(event) { 
 
    if (event.target == modal) { 
 
     modal.style.display = "none"; 
 
    } 
 
}

/* The Modal (background) */ 
 
.modal { 
 
    display: none; /* Hidden by default */ 
 
    position: fixed; /* Stay in place */ 
 
    z-index: 1; /* Sit on top */ 
 
    left: 0; 
 
    top: 0; 
 
    width: 100%; /* Full width */ 
 
    height: 100%; /* Full height */ 
 
    overflow: auto; /* Enable scroll if needed */ 
 
    background-color: rgb(0,0,0); /* Fallback color */ 
 
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */ 
 
} 
 

 
/* Modal Content/Box */ 
 
.modal-content { 
 
    background-color: #fefefe; 
 
    margin: 15% auto; /* 15% from the top and centered */ 
 
    padding: 20px; 
 
    border: 1px solid #888; 
 
    width: 80%; /* Could be more or less, depending on screen size */ 
 
} 
 

 
/* The Close Button */ 
 
.close { 
 
    color: #aaa; 
 
    float: right; 
 
    font-size: 28px; 
 
    font-weight: bold; 
 
} 
 

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

<h2>Modal Example</h2> 
 

 
<!-- Trigger/Open The Modal --> 
 
<button id="myBtn">Open Modal</button> 
 

 
<!-- The Modal --> 
 
<div id="myModal" class="modal"> 
 

 
    <!-- Modal content --> 
 
    <div class="modal-content"> 
 
    <span class="close">&times;</span> 
 
    <p>Some text in the Modal..</p> 
 
    </div> 
 

 
</div> 
 

 
</body> 
 
</html>

你需要這個例子適應您的需求。
