Simple HTML Tabs

This is a simple HTML tabbed content example, that does not use a plugin. It uses simple vanilla JavaScript which could be replaced with pure CSS3. The below code can be copied and pasted into any WordPress HTML Block. Page or any HTML file.

The following shows the HTML used.

<div class="tab-container">
  <aside class="tab-nav">
    <ul class="tabbed">
      <li class="tab-btn active" data-tab="tabOne"> Tab One</li>
      <li class="tab-btn" data-tab="tabTwo">Tab Two</li>
      <li class="tab-btn" data-tab="tabThree">Tab Three</li>
      <li   class="tab-btn" data-tab="tabFour">Tab Four</li>
    </ul>
 </aside>

<div class="tabbed-container">
  <div class="tab-content open-tab" id="tabOne">
    <h2>Tab One Content</h2>

Add a little JavaScript to switch the tabs

Throw in a little inline styling as needed

<style>

.tab-container {
    display: flex;
    flex-direction: row;
    justify-content: flex-start;
    height: 33vw;
	width: 66%;
	padding: 1.5em;
	gap: 1em;
}

aside.tab-nav {
    display: flex;
	flex-basis: 30%;
    align-self: center;
}

.tabbed{
	padding: 0;
	list-style-type: none;
}

.tabbed li {
    padding: 0.5em;
    margin: .75em auto;
    font-weight: 300;
	text-align: center;
    border: 1px solid #bbb;
    border-radius: 5px;
}

li.tab-btn.active {
    background-color: #ccc;
    color: #000;
}

.tabbed-container{
	padding: 3em;
}

.tab-content{display: none;}

.tab-content.open-tab{display: block;}
