Game artists have a name for the pixel-art version of isometric: two-to-one. Lines climb one pixel for every two across, which gives clean, stair-stepped edges instead of jagged ones. The angle is about 26.6 degrees rather than 30, and almost nobody notices, which is a nice reminder that looking right beats being exact.
Shadows that sell the weight
Edge lines deserve more attention than they usually get. A thin, slightly darker line along the bottom edges grounds each block, and a lighter line on the top edge suggests a highlight. Using currentColor for those lines means a single colour change on the wrapper restyles every outline in the scene.
Choosing the three face colours
Colour contrast still applies to illustrations that carry meaning. A bar chart drawn as blocks needs enough contrast between the bars and the floor, and labels on the faces need the same contrast as body text. Decorative scenes have more freedom, but we still avoid pale blocks on a pale background.

The tip about naming faces instead of colours saved our design system a lot of pain.
Ivo Petrov
Good question. Usually that means something is flattening the 3D context; check for overflow hidden on a parent.

The paper cube exercise sounds fun. Are the templates available somewhere?
Eli Novak
Any plans for a video version of this one?
Soren Dahl
The part about layer counts was eye-opening. Our landing page had over a hundred.
Hana Sato
Agreed, this is the part most tutorials skip.
Dana Ortiz
The templates are in the downloads section of the reference post.

I teach an intro CSS class and I am going to use this as the final project.

This finally made the order of rotations click for me. I had them the wrong way round for weeks.
