Please help me out CSS friends.

My container is 660px wide.
I've set the font size to be 10cqi.
There are 10 monospace characters.
Why isn't each of them 66px wide?

Have I misunderstood how container queries work?

So any #WebDev #Webkit #WebDesign folks: I've been hacking #HTML (and later) #CSS for almost 30 years... why is webkit showing this white hairline around the edge of an element, between the box-shadow and the box background (which are supposed to be the same colour, but the shadow ends at RGB 12, 12, 12 whereas the box background is RGB 10, 10, 10). Graphics driver issue?

I'm really tempted to just #FuckThisImUsingTables as a cutup (remember those?) with baked-in alpha png backgrounds.

For spacing values on a website – is it better to respond to font-size, or available space, or stick with static units?

You don't have to choose! Sometimes the best unit in CSS is a combination – with calc()/clamp() or min()/max() or round() & other math functions.
