gets diluted after 34.23 continuous lines of CSS code.*

CSS Architecture
Structure.
– Vars, mixins under _config ensure consistency.
– Globals folder contains non-modular global styles.
– Objects folder has the smallest modular units.
– Modules are combined Objects. Sometimes not exactly
modular but mapped to content entities.
– Layouts contain only layout (duh) information such as
width, height, margin, padding.

.m-styles__families__slider__family__rail__node

CSS Architecture
Good things:
– Self explanatory in both HTML & CSS.
– Shields object’s scope.
!
Bad things:
– Can easily get carried away with underlines.
– Verbal classes (but you get used to it).
!
Things to remember:
– Never nest selectors (to ensure specificity == 1).
– Always & only, use classes.

Same Functionality ≠ Modularity
–Elements that serve the same functionality don’t have
to be the same CSS objects.
–Otherwise it’s a game of show, hide, absolute position
elements.

.o-logo__block--left!
+fs-color(secondary, background-color)!
CSS Architecture
Using Sass to create themes:
– Too much labor to create theme variations for each
selector.
– Created Sass function to do that automatically.
!
Problems:
– Specificity issues in overriding styles (trying to
convince myself that using “!important” is ok).
– Slow compilation times.

~12secCSS loading time during development
On a frickin’ 2.8Ghz, 16GB Ram, SSD Machine.

CSS Architecture
Tips:
– Helpful to prefix classes (“o-“, “l-“, “m-“), that way you recognize their
type in markup.
– Prefix JS hooks with “js-“. That way HTML/CSS restructuring doesn’t
affect javascript functionality.
– Put all rushed code in shame.css. Always write reason of inclusion in
comments.
– Keep all z-index values in z-index.css and always use increments of 10 or
more.

Javascript
Working well with Sprockets. Eventually.
– Declare dependencies with “//=require xxx”.
– Scope everything to window.fs (and pray we don’t ever
need Node’s FS module).
– Expose modules to global window.fs.Modules object.
– Using bower-rails gem for dependencies.
