Needs attention❌ Critical: 10px body text is too small. Increase to at least 14px.
✅ Optimal line spacing: 1.50 ratio ensures comfortable reading.
✅ Strong hierarchy: Headlines are 3.0x larger than body text.
✅ Good performance: Using 1 font families keeps load times fast.
✅ Consistent design: Single font family with weight variations is a modern best practice.
⚠️ Risky: Text appears on background images without overlay protection.
