What each level asks of you
A verifier marks against these descriptors. Level 1 is free and self-directed; Levels 2 and 3 use credits and a human verifier.
L1
You can turn a component design into working markup and styles.
L2
You build a responsive page against a design system, with the states handled, and can explain the structure you chose.
L3
You set the front-end patterns and the performance budget a codebase is built to.
What counts as evidence at L2
A page you built, the design it answers and how it performs.
Evidence has to be work you did. It is attached to the request and read by the verifier — it is never published.
