mask-image

The mask property in CSS allows you to hide parts of an element. For example, if you have a black and white image, you can apply that as a mask and the black parts will force the element to be transparent on that elements. Masks can also match the alpha transparency of the mask image.

Masking GIFs with other GIFs

The other day, Cassie Evans tweeted a really neat trick that I’ve never seen before: using SVG to mask one GIF on top of another. The effect is quite lovely, especially if you happen to grab a colorful GIF and place it on top of a monochrome one:

1 Element CSS Rainbow Gradient Infinity

I first got the idea to CSS something of the kind when I saw this gradient infinity logo by Infographic Paradise. The gradient doesn't look like in the original illustration, as I chose to generate the rainbow logically instead of using the Dev Tools picker or something like that, but other than that, I think I got pretty close—let's see how I did that!

1 HTML Element + 5 CSS Properties = Magic!

Let’s say I told you we can get the results below with just one HTML element and five CSS properties for each. No SVG, no images (save for the background on the root that’s there just to make clear that our one HTML element has some transparent parts), no JavaScript.

Scooped Corners in 2018

When I saw Chris' article on notched boxes, I remembered that I got a challenge a while ago to CSS a design like it, but with rounded, scooped corners instead. So, let's see how we can do it that way instead and expand it to multiple corners while being mindful of browser support.
