Review Summary

Your solution is approved because it cleanly implements all required calendar behaviors and matches the checklist items. The calendar is correctly centered with flex, uses 31 .calendar__day elements without any modifiers on individual days, and relies on SCSS loops and pseudo-elements to generate the day numbers instead of hardcoding them. The calendar--start-day-* and calendar--month-length-* modifiers are implemented with @each and @for, and changing these classes in the HTML properly shifts the start day and hides extra days as required [CHECKLIST ITEM #1]. Visual requirements such as 100px grey squares, 1px borders, 1px gaps, and the hover state (pointer, pink background, translateY(-20px), 0.5s transition) are all correctly handled. BEM is followed with calendar as the block and calendar__day as the element, and shared numeric values are stored in variables rather than repeated, which improves maintainability. As a minor improvement outside the critical scope, you can double-check your PR description to ensure demo/test links and checklist ticks are filled in properly, but this does not block the task. Overall, this is a solid, well-structured implementation that meets the task’s functional and technical standards.
