How to Create a Responsive Navbar Sidebar

Create a Responsive Navbar Sidebar "Drawer" in Bootstrap

Bootstrap 5 introduces an official Offcanvas Component that simplifies the creation of sidebars. However, creating a sidebar without the component is still possible.

Considerations for Sidebar Navs

Sidebar navigation menus can pose various challenges:

  • Responsiveness: Should the sidebar adjust its width, visibility, or orientation based on screen size?
  • Multi-level: Should the nav items include sublevels, and how will their height be accommodated?
  • Toggling: Can the sidebar be toggled using a button or an icon?
  • Positioning: Should the sidebar be positioned alongside or behind page content?
  • Placement: Should the sidebar appear on the left or right side?
  • Scrolling: How should the sidebar scroll in relation to the page?
  • Animation: Should the sidebar slide, collapse, or fade into view?

In this specific case, instead of using col-auto on the right column, consider using col to fill the width when the menu is collapsed:

<div class="container-fluid h-100">
  <div class="row h-100">
    <div class="col-5 col-md-3 collapse width m-0 p-0 h-100 bg-dark">

Enhanced Sidebar with Fixed Width

The following updated sidebar is closer to the example you provided and features a fixed width, adaptive behavior, and a slide-left/right animation:

/* Set sidebar width */
.w-sidebar {
    width: 200px;
    max-width: 200px;
}

/* Adjust sidebar on collapsing */
.row.collapse {
    margin-left: -200px;
    left: 0;
    transition: margin-left .15s linear;
}

.row.collapse.show {
    margin-left: 0 !important;
}

/* Adjust sidebar on collapsing */
.row.collapsing {
    margin-left: -200px;
    left: -0.05%;
    transition: all .15s linear;
}

This advanced sidebar includes additional functionality:

  • Fixed width
  • Adaptive behavior (Collapses or overlays based on screen size)
  • Toggling
  • Responsive (Becomes an overlay on smaller screens)
/* Optional for overlay sidebar on small screens */
@media (max-width:768px) {

    .row.collapse,
    .row.collapsing {
        margin-left: 0 !important;
        left: 0 !important;
        overflow: visible;
    }
    
    .row > .sidebar.collapse {
        display: flex !important;
        margin-left: -100% !important;
        transition: all .3s linear;
        position: fixed;
        z-index: 1050;
        max-width: 0;
        min-width: 0;
        flex-basis: auto;
    }
    
    .row > .sidebar.collapse.show {
        margin-left: 0 !important;
        width: 100%;
        max-width: 100%;
        min-width: initial;
    }
    
    .row > .sidebar.collapsing {
        display: flex !important;
        margin-left: -10% !important;
        transition: all .2s linear !important;
        position: fixed;
        z-index: 1050;
        min-width: initial;
    }
}

How can I include CSS only on some pages? How can I include CSS only on some pages? Jun 11, 2025 am 12:01 AM

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
