Here’s a guide on how to implement a Bootstrap 4 Sticky Sidebar On Scroll Event. This effect allows a sidebar to remain fixed on the screen as the user scrolls down the page, improving navigation and user experience. Follow these steps to create your own sticky sidebar.
Step 1: Include Bootstrap 4 CSS
First, you need to include the Bootstrap 4 CSS in the <head> section of your HTML document. This is essential for utilizing Bootstrap’s grid system and styling.
<link rel=’stylesheet’ href=’https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0/css/bootstrap.css’>
Step 2: Create the HTML Structure
Next, create the basic HTML structure for your page. This includes a container, a row, and columns for both the main content area and the sidebar.
<article>
<div class="container-fluid">
<div class="row">
<div class="col">
<div class="title-section">
<h1>Basic Sticky Sidebar with Bootstrap 4</h1>
</div>
</div>
</div>
<div class="row">
<div class="col-7">
<div class="content-section">
<h2>Content Section</h2>
</div>
</div>
<div class="col-5">
<div class="sidebar-item">
<div class="make-me-sticky">
<h3>Item 1</h3>
</div>
</div>
</div>
</div>
</div>
</article>
Step 3: Add CSS Styling
Now, add the following CSS styles to control the positioning and appearance of the sidebar and its content. This includes making the sidebar sticky using position: sticky.
.content-section {
min-height: 2000px;
}
.sidebar-section {
position: absolute;
height: 100%;
width: 100%;
}
.sidebar-item {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
/* Position the items */
}
.make-me-sticky {
position: sticky;
top: 0;
padding: 0 15px;
}
/* Ignore This, just coloring */
body {
background: #fff;
}
article {
background: #f1f1f1;
border-radius: 12px;
padding: 25px 0 600px;
}
.title-section, .content-section, .sidebar-section {
background: #fff;
}
.title-section {
text-align: center;
padding: 50px 15px;
margin-bottom: 30px;
}
.content-section h2 {
text-align: center;
margin: 0;
padding-top: 200px;
}
.sidebar-item {
text-align: center;
}
.sidebar-item h3 {
background: gold;
max-width: 100%;
margin: 0 auto;
padding: 50px 0 100px;
border-bottom: solid 1px #fff;
}
That’s it! By following these steps, you should now have a fully functional Bootstrap 4 Sticky Sidebar that activates on the scroll event.
