I believe the issue is about the first example, transform: translate3d(0);, which is missing two arguments. Is that right, @Stan-Stani?

Gosh, it's been a while. But I think the gist of my comment is that there are other required properties for the effect seen in the Try It section that are not clear to someone navigating to the article from a Google search who doesn't have more context, for example.

Here's a gif demonstrating that other properties are required for the effect but they are not made clear in the article:

I don't think that's the key point of this example. Live examples almost never provide reproducible code—rather, they hold all other variables constant so you can observe the effect of this one feature in a sufficiently complicated context.

That said, we'll leave it open so (1) the invalid case can be fixed (2) maybe someone has a different opinion.
