In a previous article, we explored fancy hover effects for images that involve shines, rotations, and 3D perspectives. We are going to continue playing with images, but this time, we are making animations that reveal images on hover. Specifically, we will learn about CSS masks and how they can be used to cover portions of an image that are revealed when the cursor hovers over the image.

Here is the HTML we will use for our work:

<img src="" alt="">

Yes, that’s right, only one image tag. The challenge I like to take on with each new CSS project is: Let CSS do all of the work without extra markup.

As we go, you may notice minor differences between the code I share in the article and what is used inside the demos. The code throughout the article reflects the CSS specification. But since browser support is inconsistent with some of the features we’re using, I include prefixed properties for broader support.

Example 1: Circle Reveal

In this first one, an image sits in a square container that is wiped away on hover to reveal the image.
