Exploring Lazy Loading with Blazy Module in Drupal
Introduction
Lazy loading is a technique used to defer the loading of non-critical resources (such as images) on a webpage until they are needed. This can significantly improve page load times and user experience, especially on pages with large or numerous images. In Drupal, the Blazy module provides a convenient way to implement lazy loading for images, videos, and iframes.
In this blog, we’ll delve into the Blazy module, its features, the installation process, and how to use it to implement lazy loading on your Drupal website.
What is a Blazy Module?
