CSS Application Architecture @necolas
What’s the difference between “Architecture”, “Framework”, and “Toolkit”?
Architecture… a plan about how to structure an application.
None
Framework… an implementation of an architecture that someone can use
as the basis for a working application.
None
Toolkit / Library… a collection of pre-built patterns that can
be assembled to create an application.
None
Making architectural decisions
Client / Agency work
None
I don’t need an architecture!
None
None
Long-lived product work
No clients to blame :(
Find the right problems
Clean code! …no
“Does he ever think of anything rbut himself?”
Dealing with change
Reducing helplessness
Communicate ways of thinking
The freest human is the one who never has to
choose
1. Single responsibility 2. Extension over modification 3. Composition over
inheritance 4. Low coupling 5. Encapsulation 6. Documentation

CSS preprocessing
Automatic vendor prefixes
.Button { background: linear-gradient(…); }
.Button { background: -webkit-linear-gradient(…); background: linear-gradient(…); }
CSS variables
:root { var-button-bg: linear-gradient(…); } .Button { background: var(button-bg); }
.Button { background: linear-gradient(…); }

Nothing is perfect Nothing lasts Nothing is finished
Accept transience and imperfection
