Slide 17

Slide 17 text

Start from the upper left, right?
that works.

Slide 18

Slide 18 text

Start from the upper left, right?
that works. Styles are written based on placement in the view CSS too specific. Very fragile with placement Presentation classes in the markup Poor code reuse, if any at all. To much ‘copy pasta’ A major case of the div’itus Using IDs for styling to over-ride the cascade

OOSCSS picking up where CSS left off & where OOCSS can never go

Slide 55

Slide 55 text

These are books on Object Oriented Programming. CSS is not on one of them!

Slide 56

Slide 56 text

GREAT CONCEPT bad name • Identify reusable objects • Be semantic w/HTML • Minimize selectors • Extend your classes • ‘Style’ separate from content • ‘Content’ separate from container This is GREAT stuff

Slide 57

Slide 57 text

OBJECT ORIENTATED CSS ... shortcomings • CSS Selectors are not objects • Relies heavily on ‘presentation classes’ • Requires maintenance of DOM elements for design updates • Promotes extending in the DOM, not the CSS • Uses vanilla CSS

Slide 58

Slide 58 text

THE OOCSS PROCESS the classing of the DOM OOCSS, in short, is a process of defining standardized presentational selectors which are in turn applied to the DOM. Extensions of such selectors are then extended in the DOM for added effect. It is likely that you will see examples like what you see here. ! ! Button Generator

OOCSS FRAMEWORKS attempts to automate OOCSS CSS frameworks have been using OOCSS methods since inception. Where these fail is the insane amount of CSS selectors that by default are added to the site’s CSS. From grid systems to UI elements, CSS bloat is a real issue. Ironically this bloat is what OOCSS is supposed to address.

THE CSS DREAM redesign without DOM editing Imagine a world where new design requirements are only addressed by updating CSS? Functional modules and view templates are not edited. I don’t feel OOCSS will get us there, but OOSCSS will.

Slide 64

Slide 64 text

OBJECT ORIENTATED SCSS the future of silent selectors What if we lived in a world where the ‘object’ selectors from OOCSS can be created, but never manifest themselves as CSS until they are used in semantic application? What if we could seamlessly extend selectors in our CSS and not have to touch the DOM? What if ....

Slide 65

Slide 65 text

SASS 3.2 re-writing what we can do with CSS Extending elements in vanilla CSS is hard to track. Between nested selectors and the sheer volume alone make this an arduous task. Sass gives us clarity. The ability to really define objects in our SCSS and apply them to semantic selectors within our CSS. The dream realized. // silent classes %kung { background: green; color: yellow; } %foo { background: orange; color: red; font-size: 12px; } // selectors extending silent classes .foo_one { @extend %foo; } .foo_two { @extend %foo; } // output CSS .foo_one, .foo_two { background: orange; color: red; font-size: 12px; }
