Create a Splash Page App in HTML CSS & JavaScript

Last Updated : 26 Jul, 2024

The Splash Screen is the UI element that appears as the initial screen or the loading screen. Splash Page Application consists of a styled animative splash screen effect which automatically makes the curtain opening splash effect into the application for a specific time and renders the dynamic content once the effect is been completed. We will develop this Splash Page Animative effect using HTML, CSS, and JavaScript.

Prerequisites:

HTML
CSS
JavaScript

Approach:

Create the basic layout or structure of the application using various HTML tags like <h1>,<h3>,<div>, etc. Also, link all the essential external libraries with the CDN links.
Create the overall structure for the splash screen inside the #splash div. Add all the other animative components like Loading Spinner, title, etc.
Add CSS styling to style the splash screen, dynamic content, and other elements. Also, implement the keyframe animations for various effects like bouncing, etc.
In the JavaScript file, use the DOMContentLoaded event to initiate the Splash Screen logic. Set the loading time and hide the splash screen while displaying the dynamic content.
