[Feature] Would u like to add Preloader

[Anjaliavv51]

Description

A preloader is a visual indicator, often an animation or progress bar, that appears on a website while the page's content is loading. It's designed to keep users engaged during the loading process and to signal that the website is working as expected. Preloaders are especially useful for websites with heavy content or slow loading times to improve user experience.
