CSS overlays explained
A CSS overlay is any color, shade, image, or effect that a front-end developer may apply to an element and pseudo elements being rendered in the browser by CSS. You’ve undoubtedly experienced them. If they’re applied correctly, they can be both visually appealing as well as informative. Let’s take a look at a few different kinds of overlays and how they can be useful in your web development.
Statically positioned overlay
Images are everywhere online, and for good reason. They inform, entertain, and add to the beauty of our browsing experience. Of course, not all images are perfect right out of the box. For example, some images are so colorful or striking that they distract from important content to be displayed on the page for visitors. In this case, a static overlay with a light gray or a matching theme color with a bit of opacity would be very helpful in toning down the image. We might call this an absolutely positioned overlay.
