Breakpoint Aware Stack Block

A breakpoint aware stack block built with pure HTML and CSS that shifts between horizontal and vertical stacking depending on screen width, ensuring optimal readability and spacing without relying on JavaScript.

Usage

This component is ideal for layouts where structure should adapt across devices, such as content sections with text and actions, feature highlights, media and copy pairs, or interface blocks that need a compact mobile layout and expanded desktop presentation.

Implementation

The responsive behavior is implemented using CSS flex or grid direction changes within media queries, allowing the stack orientation to switch cleanly while preserving content order and spacing consistency.

HTML

<div class="block-stack">
  <span>Label</span>
  <button>Action</button>
</div>

<div class="block-stack">
  <span>Label</span>
  <button>Action</button>
</div>
