Bootstrap 5 Grid: Medium Breakpoint (md)

The Bootstrap 5 grid system is a powerful tool for creating responsive web layouts, and the medium (md) breakpoint plays a crucial role in designing for tablets and medium-sized devices. The md breakpoint is specifically tailored for screens 768px and above, making it ideal for layouts on larger smartphones, tablets, and small laptops.

In this tutorial, we’ll explore how to effectively use the md breakpoint to design responsive, mobile-first layouts with practical examples and tips.

What is the Medium Breakpoint in Bootstrap 5?

The medium (md) breakpoint is part of Bootstrap’s grid system and targets devices with screen widths 768px and above. Layout definitions set with md classes only take effect on devices that meet this width requirement.

Key Features of the md Breakpoint:

  1. Targets devices ≥768px.
  2. Layouts below 768px will default to smaller breakpoints or stacked layouts.
  3. Works seamlessly with other breakpoints (sm, lg, etc.) for flexible, responsive designs.

Using the Medium Breakpoint (md)

To define column behavior for the md breakpoint, use classes like .col-md-*. These classes allow you to control the width and alignment of grid columns on screens 768px and larger.

Basic Example: Medium Columns

<div class="container">
  <div class="row">
    <div class="col-md-6 bg-primary text-white text-center p-3">Column 1</div>
    <div class="col-md-6 bg-secondary text-white text-center p-3">Column 2</div>
  </div>
</div>

Explanation:

  • Default (below 768px): Columns stack vertically.
  • 768px and above: Columns align horizontally, each taking 50% of the row width.

Customizing Column Widths with md Classes

You can use .col-md-* classes to specify column widths at the md breakpoint. The * indicates the number of grid columns out of 12.

Example: Custom Column Widths

<div class="container">
  <div class="row">
    <div class="col-md-4 bg-info text-white text-center p-3">Column 1</div>
    <div class="col-md-8 bg-warning text-dark text-center p-3">Column 2</div>
  </div>
</div>

Explanation:

  • col-md-4: Column 1 occupies 4/12 (33.33%) of the row width on screens 768px and larger.
  • col-md-8: Column 2 occupies 8/12 (66.66%) of the row width on screens 768px and larger.
  • On screens smaller than 768px, the columns stack vertically.

Combining Medium with Other Breakpoints

Bootstrap’s grid system is highly customizable, and you can combine the md breakpoint with smaller (sm) or larger (lg, xl) breakpoints to create responsive designs.

Example: Responsive Grid with Multiple Breakpoints

<div class="container">
  <div class="row">
    <div class="col-12 col-sm-6 col-md-4 bg-success text-white text-center p-3">Column 1</div>
    <div class="col-12 col-sm-6 col-md-8 bg-danger text-white text-center p-3">Column 2</div>
  </div>
</div>

Explanation:

  • col-12: Stacked layout on screens smaller than 576px.
  • col-sm-6: Two columns side-by-side on screens 576px and above.
  • col-md-4 and col-md-8: Adjusts to 4/12 and 8/12 widths on screens 768px and above.

Centering Content at the Medium Breakpoint

Bootstrap provides utilities to center content horizontally within the grid at the md breakpoint.

Example: Centered Columns

<div class="container">
  <div class="row justify-content-center">
    <div class="col-md-6 bg-light text-dark text-center p-3">Centered Column</div>
  </div>
</div>

Key Classes:

  • justify-content-center: Centers the column within the row at the md breakpoint.

Adding Spacing in Medium Grids

Bootstrap 5 includes responsive utility classes for adding spacing (gutters) to grid layouts.

Example: Adding Gutters

<div class="container">
  <div class="row g-4">
    <div class="col-md-6 bg-primary text-white text-center p-3">Column 1</div>
    <div class="col-md-6 bg-secondary text-white text-center p-3">Column 2</div>
  </div>
</div>

Explanation:

  • g-4: Adds a gutter (spacing) of 24px between columns and rows.

Hiding and Showing Content at the Medium Breakpoint

Bootstrap’s visibility utilities let you control the visibility of elements based on the md breakpoint.

Example: Hiding Content Below Medium Screens

<div class="container">
  <div class="row">
    <div class="col d-none d-md-block bg-primary text-white p-3">Visible on Medium Screens and Above</div>
    <div class="col bg-secondary text-white p-3">Visible on All Screens</div>
  </div>
</div>

Key Classes:

  • d-none: Hides the element by default.
  • d-md-block: Displays the element only on screens 768px and above.

Use Cases for the Medium Breakpoint

The md breakpoint is ideal for building layouts targeting tablets and small laptops. Here are some practical use cases:

  1. Two-Column Layouts: Create two-column designs for tablets and larger devices.
  2. Feature Sections: Showcase content in a grid with equal-width columns for screens 768px and above.
  3. Forms: Arrange form fields side-by-side for better usability on medium-sized screens.
  4. Product Listings: Display products in rows of 2 or 3 for tablet devices.

FAQs About Bootstrap 5 Medium Breakpoint

1. What happens if I don’t use md classes?

If no md classes are used, the layout will fall back to the smaller breakpoints (xs or sm), typically stacking content vertically.

2. Can I mix md classes with other breakpoints?

Yes! Combining md with other breakpoints like sm, lg, and xl ensures your design is responsive across all screen sizes.

3. How do I make all columns equal height at the md breakpoint?

Use flexbox utilities like .align-items-stretch or set column heights manually using the .h-100 class.

Conclusion

The medium (md) breakpoint in Bootstrap 5 is a critical tool for designing responsive layouts for tablets and small laptops. By using .col-md-* classes and combining them with other breakpoints, you can create flexible and user-friendly designs that look great on all devices.
