THE
PROBLEM
The Gust by Willem van de Velde the Younger
@shayhowe & @darbyfreyModular HTML & CSS
COMMON PROBLEMS
• Websites have difficulty scaling
• Code becomes brittle
• Files and code bases begin to swell
@shayhowe & @darbyfreyModular HTML & CSS
WHAT’S WRONG
• Best practices aren’t exactly best practices
• Standards need to evolve
@shayhowe & @darbyfreyModular HTML & CSS
BEST BAD PRACTICES
• Avoid extra elements
• Avoid classes
• Leverage type selectors
• Leverage descendent selectors
@shayhowe & @darbyfreyModular HTML & CSS
BEST BAD PRACTICES
Avoiding classes
section	
  ul#nav	
  li	
  {...}
section:nth-­‐child(2)	
  div:nth-­‐child(7)	
  >	
  a	
  {...}
Leveraging selectors
a.btn	
  {...}
#main	
  a.btn	
  {...}
#main	
  div.feature	
  a.btn	
  {...}

@shayhowe & @darbyfreyModular HTML & CSS
SPECIFICITY?
• Specificity determines which styles are applied
• Each selector has a specificity weight
• High specificity beats low specificity
• Low specificity is key
@shayhowe & @darbyfreyModular HTML & CSS
MEASURING SPECIFICITY
Formula
• IDs, Classes/Pseudo-classes/Attributes, Elements
High Specificity (Bad)
#primary	
  #main	
  div.gallery	
  figure.media
IDs: 2, Classes: 2, Elements: 2 — Compiled: 2–2–2
Low Specificity (Good)
.gallery-­‐media
IDs: 0, Classes: 1, Elements: 0 — Compiled: 0–1–0
@shayhowe & @darbyfreyModular HTML & CSS
@shayhowe & @darbyfreyModular HTML & CSS
WATCH SPECIFICITY
• Be explicit
• Keep specificity low
• Never use IDs or !important
• Avoid nested selectors (#main	
  .spotlight	
  strong	
  span)
@shayhowe & @darbyfreyModular HTML & CSS
WATCH SPECIFICITY
Bad
