add task solution

[SylwiaLeung]

• Keyframes implemented using from/to + transform with rotate property
• Stopwatch is centered and has the correct arrows size
• All Typical Mistakes from the BEM lesson theory are checked.
• Code follows all the Code Style Rules ❗️

Review Summary

I am requesting changes because there is a direct mismatch with an explicit checklist requirement that may cause tests to fail. Specifically, in src/index.html (and corresponding SCSS), [CHECKLIST ITEM #1] requires keyframes to use transform: rotate(...), but the current implementation uses transform: rotateZ(...); please change all keyframe declarations from rotateZ(...) to rotate(...) so they match the exact requirement (for example, from { transform: rotate(0deg); } to { transform: rotate(360deg); }). This is important because automated tests and checklist checks may be looking for the rotate function by name and could treat rotateZ as non-compliant even though it behaves similarly.

While not strictly a blocker, I also recommend updating the minutes-hand animation duration from the SCSS helper (toseconds(60) → 3600s) to a literal 60min, and the speed-up version from toseconds(10) to 10min, to align exactly with the task wording and possible test expectations. Functionally, your stopwatch is otherwise very strong: it is centered, uses correct sizes and colors, BEM naming is clean, and the animations (including the speed-up modifier) behave correctly. Once you adjust the keyframes to use rotate(...) (and ideally the explicit 60min/10min durations), your solution should fully satisfy both the functional and checklist requirements—nice work overall, you are very close to completion.

This violates checklist item #1: Keyframes implemented using from/to + transform with rotate property, because you are using transform: rotateZ(0deg); instead of transform: rotate(0deg);. You should switch to rotate(...) to match the exact requirement.

Review Summary

I am requesting changes because one critical requirement from the task description is still not met, and this may cause automated tests to fail. Functionally your stopwatch looks great: the layout, dimensions, colors, animations, BEM structure, and the speed-up modifier all behave as required, and the keyframes now correctly use from/to with transform: rotate(...).

However, the minutes-hand animation duration is still expressed in seconds via the toseconds(...) helper instead of using the literal min unit that the task explicitly requires. In src/styles/index.scss, update the base .stopwatch__minutes rule to use animation-duration: 60min (replacing toseconds(60)), and in the .stopwatch--speed-up .stopwatch__minutes rule, set animation-duration: 10min (replacing toseconds(10)). This change is important because the specification and potential tests are likely checking for the min unit explicitly, not just the numerical equivalence in seconds. Once you switch those two durations to 60min and 10min, your solution should fully satisfy all stated requirements. Keep the rest of your implementation as is, since everything else aligns very well with the task.

This violates the MEDIUM requirement from the task description: the minutes-hand animation duration should be expressed as 60min, not via toseconds(60); update this include to use a literal 60min to align with the wording and potential tests.

[mateacademy-ai-mentor]

This violates the MEDIUM requirement from the task description: the speed-up minutes-hand duration should be 10min, not toseconds(10); consider replacing the helper here with a literal 10min value.
