In today’s diverse landscape of devices and browsers, building websites that work seamlessly across all platforms is a daunting task. Enter progressive enhancement, a development strategy that ensures your web applications remain functional and accessible, regardless of the user’s technology or capabilities.

By embracing this approach, we can create robust, inclusive experiences while leveraging the full potential of modern web technologies.

At its core, progressive enhancement emphasizes the separation of concerns, allowing us to build a solid foundation with HTML and CSS, and then progressively enhance the experience with JavaScript. This methodology ensures that even if JavaScript fails to load or is disabled, the essential content and functionality remain available to the user.

Let’s dive into a practical example to illustrate this concept. Imagine we’re building a simple image gallery application.

<!-- base.html -->
<div class="gallery">
  <img src="image1.jpg" alt="Image 1">
  <img src="image2.jpg" alt="Image 2">
  <img src="image3.jpg" alt="Image 3">
</div>
