Form Library · Globant Medical 2022

Accessible Form Component Library

Built a reusable component library for large medical forms. This demo starts with minimal semantics: toggle each accessibility enhancement to watch the score increase in real time.

How it works: each toggle applies a semantic fix to the form and recalculates the score from accessibility checks.
