A soft glow emphasis text effect built with pure HTML and CSS that surrounds text with a gentle luminous aura, helping important words stand out while preserving readability and visual balance without relying on JavaScript or external libraries.
Usage
This component is well suited for situations where highlighting should feel calm and refined, such as hero headlines, featured labels, promotional phrases, or UI elements that need emphasis without sharp contrast or motion heavy effects.
Implementation
The glow effect is created using CSS text shadow layers or blurred pseudo elements, carefully stacked to produce a soft halo around the characters while keeping the primary text layer crisp and lightweight.
