Create Toggleable Tabs

Step 1) Add HTML:

Example


<!-- Tab links -->
<div class="tab">
  <button class="tablinks" onclick="openCity(event, 'London')">London</button>
  <button class="tablinks" onclick="openCity(event, 'Paris')">Paris</button>
  <button class="tablinks" onclick="openCity(event, 'Tokyo')">Tokyo</button>
</div>

<!-- Tab content -->
<div id="London" class="tabcontent">
  <h3>London</h3>
  <p>London is the capital city of England.</p>
</div>

<div id="Paris" class="tabcontent">
  <h3>Paris</h3>
  <p>Paris is the capital of France.</p>
</div>

<div id="Tokyo" class="tabcontent">
  <h3>Tokyo</h3>
  <p>Tokyo is the capital of Japan.</p>
</div>
            
Copy Code

Specific tab content खोलने के लिए buttons बनाएं। <div> elements class="tabcontent" के साथ सभी डिफ़ॉल्ट रूप से छिपे हुए हैं (CSS और JS के साथ)। जब user एक बटन पर क्लिक करता है - यह tab content को खोलेगा जो इस बटन से " match" करता है।


Step 2) Add CSS:

Buttons और tab content को Style करें:

Example


/* Style the tab */
.tab {
  overflow: hidden;
  border: 1px solid #ccc;
  background-color: #f1f1f1;
}

/* Style the buttons that are used to open the tab content */
.tab button {
  background-color: inherit;
  float: left;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 14px 16px;
  transition: 0.3s;
}

/* Change background color of buttons on hover */
.tab button:hover {
  background-color: #ddd;
}

/* Create an active/current tablink class */
.tab button.active {
  background-color: #ccc;
}

/* Style the tab content */
.tabcontent {
  display: none;
  padding: 6px 12px;
  border: 1px solid #ccc;
  border-top: none;
}
            
Copy Code


Step 3) Add JavaScript:

Example


function openCity(evt, cityName) {
  // Declare all variables
  var i, tabcontent, tablinks;

  // Get all elements with class="tabcontent" and hide them
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }

  // Get all elements with class="tablinks" and remove the class "active"
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }

  // Show the current tab, and add an "active" class to the button that opened the tab
  document.getElementById(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}
            
Copy Code

Fade in Tabs:

यदि आप tab content में fade करना चाहते हैं, तो निम्न CSS जोड़ें:

Example


.tabcontent {
  animation: fadeEffect 1s; /* Fading effect takes 1 second */
}

/* Go from zero to full opacity */
@keyframes fadeEffect {
  from {opacity: 0;}
  to {opacity: 1;}
}
            
Copy Code

Show a tab by default

page load पर एक specific tab खोलने के लिए, specified tab button पर "click" करने के लिए JavaScript का उपयोग करें:

Example


<button class="tablinks" onclick="openCity(event, 'London')" id="defaultOpen">London</button>

<script>
// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();
</script>
            
Copy Code

Close a tab

यदि आप किसी specific tab को close करना चाहते हैं, तो एक button के click के साथ tab को hide करने के लिए JavaScript का उपयोग करें:

Example


<!-- Click on the <span> element to close the tab -->

<div id="London" class="tabcontent">
  <h3>London</h3>
  <p>London is the capital city of England.</p>
  <span onclick="this.parentElement.style.display='none'">x</span>
</div>
            
Copy Code

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
body {font-family: Arial;}

/* Style the tab */
.tab {
  overflow: hidden;
  border: 1px solid #ccc;
  background-color: #f1f1f1;
}

/* Style the buttons inside the tab */
.tab button {
  background-color: inherit;
  float: left;
  border: none;
  outline: none;
  cursor: pointer;
  padding: 14px 16px;
  transition: 0.3s;
  font-size: 17px;
}

/* Change background color of buttons on hover */
.tab button:hover {
  background-color: #ddd;
}

/* Create an active/current tablink class */
.tab button.active {
  background-color: #ccc;
}

/* Style the tab content */
.tabcontent {
  display: none;
  padding: 6px 12px;
  border: 1px solid #ccc;
  border-top: none;
}
</style>
</head>
<body>
