February 2026 (OpenDSA/OpenDSA) monthly summary focusing on key business-value features and stability improvements. Key features delivered include a responsive embedded exercises layout that ensures embedded content is properly aligned and usable across devices: center non-KA exercises, fix left alignment, update CSS to fit within containers, and adjust JavaScript to conditionally set iframe widths for correct alignment. This work was implemented with the commit 02c171349c5b141af09992457b943879c21c9cf1 ("Centered non-KA exercises that we're previously left aligned"). Accessibility improvements for UI controls and inputs were delivered to enhance usability and screen reader support: increased contrast for language selection buttons and added ARIA labels to radio inputs for MCQ problems. Relevant commits include 5581c79dd36d4b7defd700f0d270b692a84d8bba ("fixed button contrast when choosing coding languages") and 6830b1a24baef363929b4ea50d000b86c2b40ce1 ("add aria-label to each choice in MCq problems"). Major bugs fixed and quality improvements focus on UI accessibility and cross-device usability, reducing friction for learners and improving assistive technology compatibility. Overall impact and accomplishments: The month yielded concrete improvements in learner experience, with more consistent layouts across devices, clearer UI for language selection, and better screen reader support. These changes contribute to faster task completion, reduced cognitive load, and stronger alignment with accessibility standards. Technologies/skills demonstrated: Frontend web development with CSS for responsive layout, JavaScript adjustments for device-aware iframe sizing, and accessibility best practices (ARIA attributes, color contrast) to support WCAG guidelines.
