Worked on the w3c/csswg-drafts repository to enhance the documentation and specification clarity for CSS Query Container behavior. Focused on refining the definition of query containers by clarifying that layout containment is not required, instead emphasizing style and size containment along with independent formatting context as the primary attributes. Utilized CSS and HTML skills to update technical documentation, ensuring that changes were clearly linked and traceable for future reference. The work aimed to reduce ambiguity for implementers and support faster vendor adoption, centering on documentation consistency rather than bug fixes or new features during this period, with a strong emphasis on specification accuracy.
