Bootstrap is a popular CSS framework widely used by frontend developers to create interactive UI for web applications. Bootstrap is widely used because of its simplicity and ease to use. BootStrap allows multiple utilities to make images interactive. One of these utilities can be changing the color of the image when hovered over. Hovering is basically moving the cursor over the image. The code snippet below demonstrates how to add a black hover to an image using bootstrap.
In this method, the content-overlay class specifies the required properties of the image while the mouse hovers over it. The background property in the content-overlay class specifies the opacity of the image when the user hovers over it. The content-details class specifies the set of properties that are used for the content displayed on top of the image when the mouse hovers over it.
The second approach also deals with hovering effect but here the hovering opacity is set to 1 which means the underlying image becomes completely hidden. The overlay class contains the set of specifications for the image when hovered over. The background color is set to black. The transition time and nature is also set.
