I'm learning bootstrap4. I'm trying to realize a structure here with bootstrap NAV PILL: a tab system(but looks like buttons), you can switch tabs, under a tab there is a text content and a photo, only this photo will be shown in the left, looks like tabs system is right part, photo is left part. Problem is: 1, the first tab is active, when I click any other one, nothing happens. 2, why position-absolute does not work, photo still at right? 3, how to put text content under tabs, and horizontally align center the tab and content?
.rightpart{
border:2px solid red;
min-height:100vh;
}
.pillwrapper{
border:1px solid green;
min-height:100vh;
}
.container{
border:1px solid yellow;
min-height:100vh;
}
.content-photo{
width:200px;
left:0;
top:0;
}
Could anybody please help?

For Bootstrap 4, the 'tabs' are not actually tabbable until you include the JavaScript plugin to make the tabs work. The documentation for Bootstrap states this:
https://getbootstrap.com/docs/4.3/components/navs/#tabs
To see the tabs work, see this link from the Bootstrap documentation:
https://getbootstrap.com/docs/4.3/components/navs/#javascript-behavior
The above links show the tabs working with content associated with each tab. To have content 'under' each tab, you need to have tab-panes for the content for each tab. See this example from the Bootstrap documentation.
<ul class="nav nav-tabs" id="myTab" role="tablist">
<li class="nav-item">
<a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
</li>
<li class="nav-item">
<a class="nav-link" id="contact-tab" data-toggle="tab" href="#contact" role="tab" aria-controls="contact" aria-selected="false">Contact</a>
</li>
</ul>
<div class="tab-content" id="myTabContent">
<div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
<div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
<div class="tab-pane fade" id="contact" role="tabpanel" aria-labelledby="contact-tab">...</div>
</div>
To center the tab navigation and content under each tab, you could use CSS like below for the tab navigation (from the above example HTML).
.nav {
display: block;
margin: 0 auto;
}
With this information, your HTML should look more like this:
<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css" rel="stylesheet" />
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.css" rel="stylesheet" />
<div class="container">
<ul class="nav">
<li class="nav-item">
Button 1
</li>
<li class="nav-item">
Button 2
</li>
<li class="nav-item">
Button 3
</li>
</ul>
<div class="tab-content" id="mypillcontent">
<div class="tab-pane fade" id="content-1">
<p>Content Here</p>
<img src="https://images.pexels.com/photos/162140/duckling-birds-yellow-fluffy-162140.jpeg" alt="" class="content-photo position-absolute" />
</div>
<div class="tab-pane fade" id="content-2">
</div>
<div class="tab-pane fade" id="content-3">
</div>
</div>
</div>
</div>
