Fast websites are product decisions
Performance improves when the page architecture, content model, and interaction budget agree from the beginning.
Ship less JavaScript
Render stable content as HTML and reserve client code for interactions that change state. This lowers execution cost and makes the default experience dependable.
Give motion a job
Animation should explain hierarchy, sequence, or feedback. Transform and opacity are inexpensive; unnecessary scroll work is not.
Measure the real page
Test production assets, fonts, and third-party scripts on representative devices. Local development performance hides network and CPU constraints.
