Breaking Good Habits Harry Roberts—@csswizardry
Harry who?! •Web designer/developer •Senior UI Developer—BSkyB •@csswizardry •csswizardry.com
Necessary explanation of the cheesy, overly- cryptic talk title.
Web standards… •A great idea? Definitely! •Well intentioned? You bet!
•Ambiguous? Sadly :( •Open to interpretation? Unfortunately…
…web standards •Rules? Definitely not!
Best practices •Best for who? •What are we achieving? •What
do we really want to achieve? •Are we always solving the right problems for the right people?
Good habits? •Avoiding classes and IDs •‘Handcrafting’ our CSS •Avoiding
extra markup
Bad habits? •Classitis—using too many classes •Grid systems •Extra markup
•‘Insemantic’ class names
We’ve been solving the wrong problems for the wrong people!
None
The 4 ‘-ility’s •Maintainability •Flexibility •Extensibility •Predictability
Maintainability
Flexibility
body > div:nth-of-type(2) > article:first- child > p:first-child{ font-size:1.2em }
<p>Lorem ipsum dolor sit amet...</p>
Be ?#*@ing explicit!
.intro{ font-size:1.2em; } <p class=intro>Lorem ipsum dolor sit amet...</p>
Specific !== explicit
Extensibility
Extensible •Stop thinking in pages… •…think in components… •…then think
in abstractions.
Predictability
Expect the unexpected Always build like your client’s CMS is
a bulldozer…
None
CSS selectors
IDs •Don’t use IDs in CSS •Ever.
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.
Classes •No one uses classes except browsers and other developers
(and microformats). •Classes are neither semantic or insemantic; they’re sensible or insensible.

Grid systems
None
Abstract layout into its own layer Keep components free of
dimensions

Benefits and side- effects •Sites are faster to build… •…more
robust •…more maintainable •…more consistent •…and incidentally more efficient.
Efficiency on the client side •Reused classes are ‘performance freebies’
•Abstractions mean DRYer code; less to download and evaluate •Classes match quicker than descendants
Now what? •Solve problems for the right people. •Keep yourselves
happy and sane. •Learn when enough is enough; cut yourself some slack.
However bad you think it is, there’s always worse…
