About
Native lazy loading is a technique to load non-critical images and iframes marked with the loading="lazy" attribute only when needed.
The rel="preload" attribute on 
HTML <link> elements instructs web browsers to fetch important resources early before they are requested during page rendering.
It is commonly used to prioritize fonts, stylesheets, scripts, images, and other critical assets, helping reduce render delays and improve page loading performance.
