last week i remembered that macOS lets you set your own icons and that *I* have the power to delegitimize the professionalism of the software that runs on my machine, so here's a thread of the 16 new icons i've made so far
i really forgot how fun it was to just sit down and make art for myself :')

I just had a 🤯 moment understanding how #CSS subgrid enables a child of a grid to determine how the template of the parent grid is calculated and therefore affect the layout of its siblings within that grid 😲

✨ I just published a new post, and it’s all about one of the most mind-blowing new CSS features: subgrid.
Honestly, when I first heard about subgrid, I figured it’d be a convenient little utility. I had no idea it would solve one of the most longstanding issues I’ve had with CSS. 😮

After 7 years of selling courses, I'm finally doing a Black Friday sale.
I'd held off for from doing sales in general for all this time, but had some smart people get me on board with it, so I figured if I'm going to do it, I'll go big:
40% off + Flexbox Simplified for free.
