    Note how the typography and foreground are mixed up?
  21. Foreground border-color, color, shadow-color Wednesday, May 2, 12 you can’t

    declare text shadow color explicitly, so we have to put all text shadows in the foreground, otherwise the shadow details would be in the typography.
  22. An Object Description In Sass, we describe objects using words

    and high-level concepts, not style primitives. Wednesday, May 2, 12 Isn’t this simpler to understand if you’re reading the code? We read code more often than we write it. Be nice to your future self.

    elements are styled. • Vertical Rhythm • There is no default typography. Wednesday, May 2, 12 opt-in typography is not the industry standard approach. The industry is mostly wrong about this. Typographic inheritance can be annoying.

  47. Style Concern: Foreground • Gives color to type and borders

    • Often linked to a background Wednesday, May 2, 12 It would be nice if the relationship was .foreground {@extend .background;} but it’s not (1 foreground has many backgrounds).

  65. Naming is a Collaboration Designers must pick or approve the

    name. Unfortunately, designers are not often good at naming things. Wednesday, May 2, 12 Coders have to name everything they make, but designers don’t. Naming is a skill that must be developed. You have to learn to explain your intuition and instinct.
  66. Naming Docent Developers, your job is to help them develop

    a shared design vocabulary. Wednesday, May 2, 12 If you are a developer and a designer, you now have an excuse for talking to yourself.
  67. The Name Game Find a name that describes the intent

    of a design element, not the appearance. Wednesday, May 2, 12
  68. The Name Game A too-specific name is better than a

    too-generic name. Wednesday, May 2, 12
  69. Losing the Name Game Wednesday, May 2, 12 Sometimes you

    cannot find a good name, or you find some use of a design that doesn’t match the current name.
  70. Losing the Name Game Give up: Pick two names Wednesday,

    May 2, 12 Sometimes you cannot find a good name, or you find some use of a design that doesn’t match the current name.
  71. Losing the Name Game Give up: Pick two names Consistency:

    Change the design Wednesday, May 2, 12 Sometimes you cannot find a good name, or you find some use of a design that doesn’t match the current name.
  72. Losing the Name Game Give up: Pick two names Consistency:

    Change the design Wait: Don’t name it Wednesday, May 2, 12 Sometimes you cannot find a good name, or you find some use of a design that doesn’t match the current name.
  73. The Designer Wins Wednesday, May 2, 12 Don’t force a

    design change just because a name doesn’t match. Intuition is a tricky thing, if you trust your designer, trust their gut feeling. If you don’t trust your designer... :(
  74. Classes or IDs? Use IDs for unique page elements. Specificity

    is good when styling something specific. Wednesday, May 2, 12 not always possible to find a document order. specificity is BETTER than !important. !important is a nuclear option.
  75. Specificity Wars Time to Refactor! Wednesday, May 2, 12 Fight

    the specificity wars, by refactoring; not by rejecting specificity. Document order is not enough. Keep the same order of specificity at the same level of abstraction.
  76. Structure of a Library Module 1.Dependency Imports 2.Variables, almost always

    defaulted. 3.Functions 4.Mixins 5.Placeholder selectors 6.Style Selectors Wednesday, May 2, 12 Placeholders: only import once or use the mixin hack if your module has these Selectors: Usually don't mix with Functions/mixins/placeholders
  77. Breaking the Rules ‣Experiment with new designs ‣Accommodate non-conforming design.

    ‣Build what you need today ‣Meet your deadlines ‣Diligently factor out what is common Wednesday, May 2, 12
  78. Documentation ‣It's better to show than to tell. ‣Make a

    living styleguide for documentation and prototyping. ‣This is your design catalog. ‣Teach the design, don't just exemplify it. Wednesday, May 2, 12
  79. Downsides ‣Learning curve ‣Harder to debug ‣Classitis ‣A lot of

    work Wednesday, May 2, 12 1-2 days of training to become capable. 3-4 weeks to be competent. It will take > 1 month for an experienced team to build a comprehensive styleguide.
  80. Benefits Efficient communication Wednesday, May 2, 12 More efficient team

    thru better communication thanks to new vocabulary. completely Describing a page design can be done in ~5 minutes.
  81. Benefits Low Coupling Wednesday, May 2, 12 a clean separation

    in responsibilities, means changes breaks things less often in unexpected ways
  82. Benefits Built to last Wednesday, May 2, 12 These styles

    will be used for > 2 years. These styles will be used by a team. For the love of god, don't do this for your blog or a marketing/promotional site.
