Review Summary
I am requesting changes because several critical requirements are missing or incorrect, which blocks the stopwatch from meeting the task and test expectations. Specifically: 1) The main styles for .stopwatch, .stopwatch__hand--second, .stopwatch__hand--minute, .stopwatch__center, and the modifier .stopwatch--speed-up are not implemented (size 80vmin, 1vmin dotted #000 border, vertical/horizontal centering, hand lengths/widths/colors, center circle 5vmin #f6a603, infinite animations, starting position at top). 2) The keyframes in animations.scss use 0%/100% and include translateX; the requirement is to use from/to and only rotate in transform [CHECKLIST ITEM]. 3) The animation timings/functions are missing: seconds must be 60s linear per full rotation and minutes must be 60min steps(60), with the .stopwatch--speed-up modifier changing these to 10s and 10min. 4) Visual regression tests fail due to these style/animation gaps.
What to fix: - Replace keyframes with from { transform: rotate(0deg); } to { transform: rotate(360deg); } in animations.scss. - Add SCSS to center the stopwatch and set its size and dotted border. - Define hands with exact dimensions/colors, set transform-origin to the center, ensure they start pointing up, and apply infinite animations with the specified durations and timing functions. - Implement .stopwatch--speed-up to override durations to 10s (seconds) and 600s/10min (minutes). Once these are in place, rerun Backstop tests and adjust styles until diffs pass. You’ve got the HTML structure right—finish the CSS details and you’ll meet all requirements.

The HTML includes the required element with class stopwatch and the stopwatch--speed-up modifier which tests expect. However, many visual and animation requirements are missing because corresponding CSS/SCSS is not provided. Implement styles for: center the stopwatch (vertically and horizontally); set its size to 80vmin by 80vmin; add a 1vmin dotted round border with color #000; create minute and second hands with the exact lengths, widths and colors (minute: 20vmin length and 3vmin width, color #0700ff; second: 38vmin length and 1.5vmin width, color #2c8000); ensure the starting position of hands is at the top; add the center circle of diameter 5vmin and color #f6a603; animate infinitely; seconds hand must use a linear animation of 60s per full circle; minutes hand must use steps(60) over 60min; create rules for the stopwatch--speed-up modifier to change durations to 10s and 10min. Without these styles the task requirements are not met.

The task requires keyframes implemented using from/to + transform with rotate property (checklist item). Your keyframes use percentage syntax (0%/100%) instead of from/to. Also the keyframes include translateX which mixes positioning with rotation — the requirement expects rotate in transform for the keyframes. Please replace the @Keyframes with from/to and ensure transform contains rotate only (e.g. from { transform: rotate(0deg); } to { transform: rotate(360deg); }).

Only the animations.scss file is provided but it doesn't satisfy the 'from/to' keyframes constraint and it's insufficient alone. Ensure you add/adjust CSS rules for .stopwatch, .stopwatch__hand--second, .stopwatch__hand--minute, .stopwatch__center, and the modifier .stopwatch--speed-up to change animation durations as specified in the description.

Review Summary
I am requesting changes because key CSS required for the stopwatch visuals and behavior is missing, which blocks the core functionality. While your HTML includes .stopwatch and the .stopwatch--speed-up modifier and the keyframes are correct, the styles that define size, border, hands, center, and animation timings are not implemented.
Critical issues to fix:
- Define
.stopwatchwith centering,width/height: 80vmin, andborder: 1vmin dotted #000(index.scss/stopwatch.scss). This satisfies the visual container requirement. - Add
.stopwatch__hand--secondand.stopwatch__hand--minutewith exact specs: seconds length38vmin, width1.5vmin, color#2c8000; minutes length20vmin, width3vmin, color#0700ff. Settransform-originsorotate(0deg)points straight up from the center (e.g., position the base at the center and rotate around it). - Apply animations: seconds hand
animation: <seconds-keyframes> 60s linear infinite; minutes handanimation: <minutes-keyframes> 60min steps(60) infinite. Ensure the hands start at the top. - Implement
.stopwatch__centeras a centered circle5vmindiameter with background#f6a603. - Implement the
.stopwatch--speed-upmodifier to override durations to10s(seconds) and10min(minutes) via more specific selectors or CSS variables.
Minor: Ensure your SCSS structure imports all partials (variables, animations, stopwatch) so styles compile. You’re close—once these styles are added with exact units and colors, the stopwatch should meet all requirements. Keep up the good work!

The HTML includes the required stopwatch block and the stopwatch--speed-up modifier — this satisfies the requirement to have an element with class stopwatch and the modifier present for tests. No change required here.

You need to define .stopwatch__hand--second and .stopwatch__hand--minute with the exact sizes and colors from the task: seconds length 38vmin, width 1.5vmin, color #2c8000; minutes length 20vmin, width 3vmin, color #0700ff. Also set appropriate transform-origin so the hands start from the center and point to the top initially (rotate(0deg) should correspond to top).

The center element .stopwatch__center is missing styling: define it as a circle with diameter 5vmin and background color #f6a603, positioned at the center of the stopwatch.

Implement the .stopwatch--speed-up modifier to override the animation durations: seconds should be 10s and minutes 10min when the modifier is present (e.g. via more specific rules or CSS variables). The modifier exists in HTML but its CSS behavior is missing.

The keyframes in animations.scss are correctly written using from/to and transform: rotate(...), matching the checklist item: "Keyframes implemented using from/to + transform with rotate property."

Make sure the seconds hand animation uses a linear timing function and duration 60s (and infinite). The minutes hand must use animation-timing-function: steps(60) (or animation: ... steps(60)) and duration: 60min (and infinite). Also implement overrides in .stopwatch--speed-up to set seconds to 10s and minutes to 10min.
