   •Ambiguous? Sadly :( •Open to interpretation? Unfortunately…

7. …web standards •Rules? Definitely not!

14. Maintainability

15. Flexibility

17. Be ?#*@ing explicit!

18. .intro{ font-size:1.2em; } <p class=intro>Lorem ipsum dolor sit amet...</p>

    in abstractions.

21. Predictability

24. CSS selectors

25. IDs •Don’t use IDs in CSS. •Ever.

26. IDs •No advantage over classes. •Waaaaaay overly specific. •Not dissimilar

    to !important •Everything you can do with an ID can be done with a class.

27. Classes •No one uses classes except browsers and other developers

    (and microformats). •Classes are neither semantic or insemantic; they’re sensible or insensible.
