During the month, contributed to the freeCodeCamp/freeCodeCamp repository by delivering a focused curriculum enhancement centered on CSS color handling. The work involved clarifying the use of HSLA alpha values as percentages, directly addressing ambiguity in the Color System: HSLA Alpha Percentage Usage section. By updating instructional content and refining the HSL lesson, the changes improved both the accuracy and accessibility of CSS color transparency concepts for learners. Leveraging front end development skills and Markdown, the contribution reduced student confusion and support requests, reinforcing best practices in CSS. The effort emphasized curriculum quality and consistency without introducing new bugs or regressions.
