Flexbox and Box Model lessons: - Use explicit task instructions with selector AND property - Include selector in codePrefix for better context - Replace hex colors with named CSS colors (steelblue, coral, etc.) - Simplify values (2px instead of 0.125rem, 1rem instead of 1.25rem) - Remove redundant contains validations - Wrap code examples in <code> tags for proper styling
