Brand New Layouts with CSS Subgrid • Josh W. Comeau
Subgrid allows us to extend a grid template down through the DOM tree, so that deeply-nested elements can participate in the same grid layout. At first glance, I thought this would be a helpful convenience, but it turns out that it’s so much more. Subgrid unlocks exciting new layout possibilities, stuff we couldn’t do until now. ✨

Time-based CSS Animations
In my earlier post Time Uniform For CSS Animation,
I took a note about a way to do CSS animations with time ticks instead of keyframes.
It was limited applicable because CSS lacked the ability of doing complex Math calculations.
After years of wait, CSS now has enough Math functions supported,
particularly mod(), round(),
and trigonometric functions.
It's time to revisit the time-based way of animation, hope it'll be more useful this time.
