Animated “Generating” Text Loader Using Only HTML and CSS

This creative loading animation presents the word “Generating” in a visually engaging way, combining animated letters with a moving light effect. It’s built entirely with HTML and CSS, making it lightweight and perfect for modern websites that want a custom preloader or transition screen without relying on JavaScript.

How the Layout Works

The loader consists of two main parts:

1. Individual Letters – Each letter in the word “Generating” is separated into its own span element. This setup allows each character to animate independently.

2. Visual Loader Layer – Behind the letters, a visual effect is added using gradients and mask layers, creating a glowing motion that passes across the text.

Animation Breakdown

Each letter fades in and out on a loop using keyframe animation. The effect includes subtle changes in opacity, a soft glowing text shadow, and a slight movement upward, which makes the text feel lively and dynamic. Every letter has a unique delay, creating a wave-like motion across the word.

Meanwhile, the background loader animates from left to right with layered radial gradients. These create colorful circular bursts that move across the entire wrapper. A masking technique is used to reveal and hide the gradient in specific patterns, giving the illusion of light flickering or sweeping through the loader.

Visual Details

• Font and Style: The animation uses a clean sans-serif font with a bold weight to make each letter pop.

• Color and Glow: The letters use white text with soft shadows when active, creating a neon-like flash.

• Scaling Effect: A gentle scaling and vertical movement is applied when letters appear, adding depth to the animation.

• Timing and Delay: The animation timing is carefully staggered across letters to make the appearance feel organic rather than mechanical.

Background Light Movement

The loader behind the letters adds extra visual interest. It uses multiple radial gradients with bright colors like yellow, red, blue, cyan, and green. As the animation plays, these colors shift horizontally across the background, masked by a transparent gradient that gives the illusion of soft, glowing lights moving across the letters.

Practical Use

This type of animation works great for loading screens, file generation messages, or waiting periods in creative tools. Because it’s entirely CSS-based, it performs well and is easy to customize. You can change the word, speed, colors, or glow effect by editing just a few style rules.

This animated loader adds a stylish and futuristic touch to any interface, keeping users visually engaged during wait times — all using just HTML and CSS.
