Rethinking Text Resizing on Web

Airbnb is committed to improving web accessibility, specifically focusing on Resize Text guidelines for users with low vision. The challenges of implementing these changes for mobile web are highlighted, as browser zoom can lead to layout issues. The use of rem units for font scaling is explored, offering a more consistent and predictable approach compared to px and em units. The transition to rem units was facilitated through automation and tooling. The impact of these accessibility improvements resulted in the resolution of over 80% of Resize Text issues. Airbnb continues to prioritize accessibility and invites those interested in such challenges to consider career opportunities with the company.
