Overlay Effect with Color
- Define a container div for the image with nested elements for overlay and content.
- Style the image container to position elements and set image dimensions.
- Create an overlay with a semi-transparent background using CSS.
- Initially, set the overlay’s opacity to 0 to make it invisible. On hover, change the opacity to reveal the overlay.
- Position the content div within the container. Style the text content for visibility and aesthetics.
Example: The example below shows how to create overlay effects with the CSS colour.
