Scenario
你正在为一个技术博客设计文章阅读页面。
设计要求：
- 文章需要良好的可读性
- 标题需要层次分明
- 段落之间有合适的间距
- 代码片段需要等宽字体
Why Do This
- CSS is fundamentally about constraining layout and visual hierarchy, not memorizing properties.
- Clarify the box model and layout rules first, then add visual polish — less rework that way.
- Writing styles as reusable patterns is more valuable than tweaking a single page.
Hands-on Practice
- Write the layout skeleton first (display/gap/align), then add colors and shadows.
- Extract repeated styles into reusable classes.
- Use validation rules to reverse-engineer the design intent of your current styles.
Common Mistakes
- Adding margin after margin to fix positioning while ignoring layout containers.
- Selectors nested too deep, causing style coupling.
- Only caring about how it looks without considering maintainability.
Deliverable
A reusable component style template (layout rules + visual rules + naming conventions).
