Overlay

An overlay is a semi-transparent layer placed on top of an image or element, often used in web and graphic design to enhance visual appeal and functionality. This layer allows designers to highlight important content, provide additional information, or create a specific mood without completely obscuring the underlying image. Overlays can serve various purposes, such as drawing attention to call-to-action buttons, improving text readability against complex backgrounds, or adding a sense of depth and dimension to a design. By adjusting the opacity and color of an overlay, designers can achieve different visual effects that contribute to a cohesive and engaging user experience. Overlays are commonly used in websites, mobile applications, and digital media to balance aesthetics and usability.
