Spent 3 hours on a circle shadow before I realized my math was wrong

I was trying to make a neon glow effect around a perfect circle in pure CSS, thinking it would be a 10 minute job. Kept getting this weird flat spot on the bottom right corner that drove me nuts. After messing with border-radius and box-shadow for way too long, I realized my circle's width and height were off by 2 pixels because I used a percentage instead of a fixed unit. Anyone else ever waste that much time on something this dumb?

Oh man, percentage vs fixed units always messes me up too. Did you catch it because the shadow looked off or did you actually measure the pixels?

Hold up, TWO pixels?! That's wild. I would've been staring at that flat spot for hours too before I ever thought to check the actual math.
