A radial highlight background built with pure HTML and CSS that applies a soft circular glow behind content areas. It enhances focused visual emphasis and layered depth clarity within modern UI sections.
Usage
Use this component when interfaces require center weighted background emphasis, such as hero sections, call-to-action blocks, login panels, or feature highlights that benefit from spotlight style styling.
Implementation
The effect is implemented using CSS radial gradient techniques with controlled opacity and blur transitions, creating a smooth highlight that blends into the surrounding background. Responsive styling ensures consistent scaling across breakpoints.
