A Short Guide to Minimal Web Development

User-Centered Web Development

When we think of user focus we easily think of usability tests, following a usually strong wish to produce something that’s actually useful. For us as web developers, focus on the user has a tendency to appear distant though…

The Two Extremes of Writing CSS, and What We Can Learn from Them

Extremes can be useful. In practice they help get the maximum out of a given approach, and in theory they can show what we’re headed to. Compare two ways of writing CSS—like Tachyons or Atomic CSS, and 2000’s idealistic engineering.
