Hello readers, Today in this blog you'll learn how to create an Animated Gradient Shiny Loader or Preloader in HTML CSS & JavaScript. Earlier I have shared a Color Changing Shiny Loader using HTML & CSS only Now it's time to create an Animated Gradient Loader with Percentage in JavaScript.

Preloaders are what you inspect on the screen while the rest of the page’s content is still loading. Preloaders or loaders are often easy or complex animations that are used to keep visitors entertained while server operations finish processing.

At first, this loader is in the initial stage, where there is a loader and 0% text or number at the center on the webpage. But when you click on that center text or number, the loader will be activated and it starts to rotates as well as the center percentage also starts to increase from 0% to 100%. When it completed 100%, the loader stops to rotating.

Preloader in HTML CSS & JavaScript [Source Codes]


As always, before sharing the codes of this program (Animated Gradient Shiny Loader). Let's a few talk about the main tags and codes of this program. As you already know, this loader based on HTML CSS & JavaScript. In the HTML File, first I created a <div> with the class name "outer". Then I created another <div> with the class name "inner" and placed a <span> tag inside it.

In the CSS File, first I placed all elements at the center using Flex property and set background-color and font-family to the body.  After that, using @keyframes property I rotate or animate this loader 360deg. The @keyframes rule specifies the animation code. During the animation, you can change the set of CSS styles several times.

In the JavaScript File, first I called all elements using their class name. Inside this function, I created a setInterval function. The setInterval() method calls a function or estimates an expression at particularized intervals (in milliseconds). The setInterval() method will proceed to call the function until clearInterval() is called, or the window is closed. Inside the setInterval function, I created if/else statement. Inside if statement, I wrote a condition if count == 100 then run this statement otherwise go to else statement. Inside else statement, I start loader and rotates it clockwise.

To create this program (Animated Gradient Shiny Loader). First, you need to create two Files one HTML File and another one is CSS File. After creating these files just paste these following codes in your file.
