Estelle focused on improving documentation reliability in the mdn/rari repository by addressing a broken link within the CSS syntax documentation. She identified an inconsistency in the slug naming convention, where CSS_Values_and_Units needed to be updated to CSS_values_and_units, and implemented the fix using Rust. This adjustment ensured that generated documentation links now direct users to the correct resource, reducing navigation errors and support overhead. Her work reinforced consistency across CSS references and improved maintainability for future documentation updates. Estelle’s contribution, while targeted and limited in scope, demonstrated attention to detail in documentation practices and technical proficiency with Rust.
