The session was originally titled "Managing Complex Projects with Design Components”, but the training I took to become a certified ScrumMaster blew my mind. Integrating agile development with web development is actually very simple. It's called Styleguide-Driven Development. In this session, we will discuss the two requirements for Style Guide Driven Development: component-based design and automated style guides.

.menu .item a:link {}!
.sidebar .menu .item a:link {}!
.page-37 .sidebar .menu .item a:link {}

.menu .item a:link {!

25. OVERLY GENERIC CLASS NAMES
.title&{&}
.block&.title&{&}
.node&.title&{&}

.content&{&}
.block&.content&{&}
.node&.content&{&}

26. SEEMED LIKE A GOOD IDEA
AT THE TIME

27. WHAT IS A DESIGN COMPONENT?
“Component” is the same as…
⨯ “Object” in OOCSS
⨯ “Module” in SMACSS
⨯ “Block” in BEM’s Block-Element-Modifier
⨯ “UI Pattern”

28. CSS DESI GN COMPONENTS ARE:
⨯ Applied to a loose collection of HTML elements
⨯ Repeatable
(even if never repeated)
⨯ Specific
Replace CSS specificity with specific names
⨯ Self contained
Styles do not bleed onto anything else
⨯ Nest-able

36. “You see, radio is a kind
of a very, very long . cat.

37. You pull his tail in New
York and his head is
meowing in Los Angeles.

38. Do you understand this?
You send signals here, they
receive them there. The
only difference is that…

39. …there is no cat.”
— Albert Einstein

47. On semantic naming
⨯ Content semantics
are handled by HTML5 elements
⨯ Let’s make our class names use
Design semantics
⨯ Class names should be meaningful to
developers and designers

61. SIMPLE FOLDER STRUCTURE

62. EASY TO FIND YOUR COMPONENTS.
⨯ Inspect the DOM.
⨯ Find the CSS class on the
component.
⨯ Look for a file with that
name in the components
folder.
