Structural simplicity is not necessarily visual simplicity. Modular devices are structurally simple, but often physically bulky. MacBook power bricks are visually simple, but structurally too complex to be repaired.
Philosophically, structural simplicity is the one to prioritise. Form follows function.
Designing a webstead around the avoidance of CSS leads to a reduction in bloat and an improvement in structure.
It also makes plain sense. Visitors are already setting their preferences, whether font size, color theme, or window width. I’m just extending this way of thinking to style sheets, which can be customised thru browsers.
I’m happy to have my webstead listed in the No-CSS Club. Some day, this blog too will wave goodbye to cascades.
