Image Overlays
Image overlays are a graphical technique where one or more images, text, or graphical elements are superimposed on top of a base image to create a composite visual. This is commonly used in web design, photo editing, and user interfaces to add effects, annotations, branding, or interactive elements. It enables dynamic content presentation without altering the original image data.
Developers should learn image overlays for creating visually engaging web applications, such as adding watermarks, tooltips, or interactive hotspots on images. It's essential in UI/UX design for features like image galleries with captions, social media apps with filters, and e-commerce sites displaying product badges. Mastering overlays improves front-end development skills for responsive and interactive media.
