Description
Lazyline is a lightweight WordPress plugin designed to improve site speed by deferring the loading of below-the-fold images, videos, and iframes until they enter the visitor’s viewport. Instead of loading everything upfront, it helps reduce initial page work and supports smoother browsing on both fast and slower connections.
Built with plain “vanilla” JavaScript and the IntersectionObserver API, Lazyline adds performance-friendly lazy loading behavior without adding heavy dependencies. It also supports responsive images and can enable native lazy loading, helping your WordPress and WooCommerce pages feel faster while contributing to better Core Web Vitals.
