 Here's a really neat effect. Watch the background color on the text input and the icons here. See how they're sort of desaturated there in the middle? But as I pull them to the outer edges, they get more vibrant. And at the top, it was green. And at the bottom, it was red and orange. What is this magic? It's called background attachment fixed. And I can't wait to show you about it. To help us understand what's happening, let's get the HTML, the same gradient. And now we can see what's happening. Background attachment fixed is making this full viewport gradient. And every icon's background is a window into that. That position of those icons is telling it which part of the gradient to let shine through. And look as we change all the gradients, we can see that effect and how it works. But if we look down at the selectors with the icon button before and footer input, there's the background and there's background attachment fixed. The background attachment fixed property is the crucial thing to make this all work. And I just think it's underused. I hope you enjoyed this gooey snippet and I'll see y'all on the internet.
