An inset shadow effect built with pure HTML and CSS that applies inner shading to simulate a recessed surface. It enhances contained depth perception and surface contrast clarity without modifying layout structure.
Usage
Use this component when interfaces require recessed styling emphasis, such as input fields, panels, containers, cards, or UI controls that benefit from subtle inner depth cues.
Implementation
The effect is implemented using CSS inset box shadow properties, carefully adjusted for blur, spread, and opacity to create controlled inner shading. Responsive styling ensures consistent rendering across screen sizes.
