Summary
The article discusses the complexity and challenges of CSS layout systems, questioning whether CSS should be fundamentally rethought as a constraint-based system rather than its current approach. The author, who has formal expertise in CSS specification, examines historical layout problems like the 'Holy Grail' layout and centering divs, suggesting that CSS's current model might be fundamentally flawed and proposing that a constraint-based approach could offer a more intuitive solution for web layout design.
