3. ?Why Architecture

4. #news h2 { border-bottom: 1px solid black; padding: 1em 0.5em; font-size: 18px; font-weight: bold; }

5. #news h2 { border-bottom: 1px solid black; padding: 1em 0.5em; font-size: 18px; font-weight: bold; } ! #faq .title { border-bottom: 1px solid black; padding: 1em 0.5em; font-size: 18px; font-weight: bold; }

6. #news h2 { border-bottom: 1px solid black; padding: 1em 0.5em; font-size: 18px; font-weight: bold; } ! #faq .title { border-bottom: 1px solid black; padding: 1em 0.5em; font-size: 18px; font-weight: bold; } ! #service .feature .title { border: 1px solid black; padding: 0.5em; font-size: 16px; }

7. .column_2 #inbox .list { ... } .column_3 #inbox .list { ... } .column_3 #inbox .list .name { ... } .column_3 #inbox .list .name p { ... } .column_3 #inbox .list .name.reply { ... } .column_3 #inbox .list .name.reply a { ... } body#top .column_3 #inbox .list.left { ... }

8. !important

9. Goals of Better CSS Architecture -Predictable -Reusable -Maintainable -Scalable http://article.enja.io/articles/css-architecture.html 予測しやすい再利用しやすい保守しやすい拡張しやすい

10. Modular CSS

11. OOCSS Nicole Sullivan https://github.com/stubbornella/oocss/wiki

12. OOCSS -Separate structure and skin -Separate container and content 構造と見た目の分離コンテナとコンテンツの分離

13. Media object

14. <div class="media"> <div class="media-image"> <img src="/img/seminar/15/tani.jpg"> </div> <div class="media-body"> <p>...</p> <ul> <li><a>...</a></li> </ul> <p>...</p> </div> </div>

17. .media { /* Clearfix */ } .media-image { float: left; margin-right: 10px; } .media-image > img { display: block; } .media-body { overflow: hidden; }

18. <div class="media skin-a"> <div class="media-image"> <img src="/img/seminar/15/tani.jpg"> </div> <div class="media-body"> <p>...</p> <ul> <li><a>...</a></li> </ul> <p>...</p> </div> </div>

19. <div class="media skin-b"> <div class="media-image"> <img src="/img/seminar/15/tani.jpg"> </div> <div class="media-body"> <p>...</p> <ul> <li><a>...</a></li> </ul> <p>...</p> </div> </div>

20. ?How to build modules

21. It depends.

22. Rule of Three ‘Refactoring’ http://en.wikipedia.org/wiki/Rule_of_three_(computer_programming)

23. 3, 6

24. 3, 6, 9, 12, 15 ...

25. 3, 6, 12, 24, 48 ...

26. 3, 6, 9

27. 3, 6, 9, 12, 15 ...

28. .fontSize10 { font-size: 10px } .colorRed { color: red }

29. <p class="fontSize18 colorRed"> 入力内容に誤りがあります。 </p>

30. <p class="box radius10 fontSize18 colorRed"> 入力内容に誤りがあります。 </p>

31. .fontSize18 { font-size: 18px }

32. .fontSize18 { font-size: 18px } ! @media only screen and (max-width : 320px) { .fontSize18 { font-size: 14px } } ⚠

33. .colorRed { color: red }

34. .colorRed { color: orange; } ⚠

35. .colorRed { color: orange; /* あとで直す */ } ⚠
